Deseja instalar e configurar o W3 Total Cache em seu site WordPress?
O W3 Total Cache é um popular plug-in de cache do WordPress que ajuda a melhorar a velocidade e o desempenho do seu site. Os plug-ins de cache podem ajudar a reter usuários e reduzir as taxas de rejeição, o que pode ajudar o SEO e aumentar as conversões.
Neste guia para iniciantes, mostraremos como instalar e configurar facilmente o W3 Total Cache em seu site WordPress.
Nota do editor: Não usamos mais o W3 Total Cache em nosso site e mudamos para o WP Rocket, que é um plugin de cache premium. O W3 Total Cache ainda é uma boa solução que funciona bem.
O que é o W3 Total Cache?
O W3 Total Cache é um dos melhores plug-ins de cache do WordPress que permite melhorar facilmente o desempenho e a velocidade do WordPress.
Por padrão, o WordPress usa PHP para gerar dinamicamente cada página do seu site quando ela é solicitada por um usuário.
O PHP é uma linguagem de programação do lado do servidor. Isso significa que cada solicitação do usuário aumenta a carga no seu servidor. Isso afeta o desempenho, a experiência do usuário e o SEO do seu site.
Os plug-ins de cache do WordPress ajudam a reduzir esse problema, ignorando o PHP e fornecendo uma cópia em cache da sua página da Web.
Ele também permite que você conecte facilmente seu site a uma CDN (rede de distribuição de conteúdo) para melhorar ainda mais o desempenho do site.
Instalação do W3 Total Cache no WordPress
Antes de instalar o plug-in W3 Total Cache no WordPress, é necessário certificar-se de desativar qualquer outro plug-in de cache no seu site. Isso o ajudará a economizar recursos do servidor e evitará conflitos de plugins.
Depois disso, você pode prosseguir e instalar e ativar o plug-in W3 Total Cache. Para obter mais detalhes, consulte nosso guia passo a passo sobre como instalar um plug-in do WordPress.
Após a ativação, o W3 Total Cache adicionará um novo item de menu chamado Performance à barra lateral de administração do WordPress. Ao clicar nele, será iniciado o assistente de configuração do plug-in.
Basta clicar no botão Next para continuar.
Primeiro, você será solicitado a ativar o Page Cache. Clique no botão Test Page Cache para continuar.
O W3 Total Cache mostrará a você diferentes opções de mecanismo de armazenamento. Você precisa escolher aquele que lhe poupará mais tempo. Normalmente, será a opção “Disk: Enhanced” para a maioria das plataformas de hospedagem compartilhada.
Clique no botão Next para continuar.
Agora, você terá a opção de testar o cache do banco de dados. Recomendamos escolher None (Nenhum). Para a maioria dos sites de pequeno e médio porte, o servidor MySQL poderá buscar dados mais rapidamente do que o cache do banco de dados.
Clique no botão Next para passar para a próxima etapa.
Isso o levará à seção Object Cache. O Object Caching permite que o W3 Total Cache armazene consultas ao banco de dados para páginas dinâmicas e as reutilize para melhorar o desempenho.
Se o resultado do teste mostrar uma diferença de apenas alguns milissegundos, você poderá escolher None (Nenhum).
Clique no botão seguinte para continuar.
Depois disso, clique no botão Test Browser Cache (Testar cache do navegador) e selecione a opção “Enabled” (Ativado) nos resultados do teste.
Essa opção solicita que o navegador do usuário armazene uma cópia da página da Web por um tempo limitado. Carregar uma página do cache do navegador é muito mais rápido do que carregá-la do cache do servidor da Web.
Clique no botão next para passar para a próxima etapa.
Por fim, o assistente de configuração solicitará que você ative o carregamento lento para imagens.
Agora, o WordPress vem com carregamento lento integrado para imagens. No entanto, alguns navegadores mais antigos podem não ter suporte para esse recurso.
O W3 Total Cache usa JavaScript para adicionar carregamento lento para imagens, o que pode ser ainda mais rápido e eficiente.
Depois disso, clique no botão Next (Avançar) para concluir o assistente de configuração e visualizar o painel do W3 Total Cache.
Opções avançadas de cache no W3 Total Cache
As configurações básicas funcionariam para a maioria dos sites. No entanto, há muitas opções avançadas que você pode configurar para melhorar ainda mais o desempenho.
Vamos dar uma olhada nas mais importantes.
Reduzindo JavaScript e CSS no W3 Total Cache
O termo “minify” é usado para descrever um método que reduz o tamanho dos arquivos do seu site. Ele faz isso removendo espaços em branco, linhas e caracteres desnecessários do código-fonte.
Observação: a redução dos arquivos JS e CSS pode danificar seu site. Se você ativá-la e seu site não parecer correto, basta desativar essas opções.
O W3 Total Cache também permite que você reduza facilmente o código-fonte JavaScript, CSS e HTML. Entretanto, recomendamos que você reduza apenas os arquivos JavaScript e CSS.
Basta acessar a página Performance ” Minify e rolar para baixo até a seção JS.
Marque a caixa ao lado de “JS minify settings” para ativá-la.
Agora, role para baixo até a seção CSS e ative as configurações de redução de CSS da mesma forma.
Não se esqueça de clicar no botão Save All Settings (Salvar todas as configurações) para armazenar suas configurações.
Para obter métodos alternativos, consulte nosso guia sobre como reduzir os arquivos JavaScript e CSS no WordPress.
Ativar o suporte a CDN no W3 Total Cache
As CDNs ou redes de distribuição de conteúdo ajudam a melhorar ainda mais o desempenho do seu site, fornecendo arquivos estáticos, como imagens, CSS e JavaScript, a partir de uma rede global de servidores.
Isso reduz a carga no servidor de hospedagem do WordPress e melhora a velocidade de carregamento da página.
O W3 Total Cache vem com suporte integrado para várias plataformas CDN.
Recomendamos o uso do Bunny.net, que é a melhor solução de CDN do mercado. É o que usamos em nosso site OptinMonster.
Primeiro, você precisa se registrar em uma conta Bunny.net. Após o registro, é necessário criar uma Pull Zone para o seu site.
Uma pull zone adiciona um nome de host ao Bunny.net CDN. Esse nome de host é usado para fornecer arquivos estáticos para seu site.
Adicione um nome para sua pull zone e, em seguida, forneça o nome de domínio do seu site.
Depois de adicionar a pullzone, você precisa acessar a página Desempenho ” Configurações gerais.
Em seguida, role a tela para baixo até a seção CDN.
Marque a caixa Enable (Ativar) ao lado da opção CDN e escolha Generic Mirror (Espelho genérico) ao lado da opção CDN Type (Tipo de CDN).
Não se esqueça de clicar no botão Save All Changes (Salvar todas as alterações) para armazenar suas configurações.
Em seguida, você precisa visitar a página Performance ” CDN e rolar para baixo até a seção Configuration: Objects.
Aqui, você precisa adicionar o nome de host que criou anteriormente para a pullzone e clicar no botão test mirror.
O W3 Total Cache verificará a disponibilidade de seu nome de host e exibirá a mensagem Test Passed quando for bem-sucedido.
Agora você pode clicar no botão Save All Changes (Salvar todas as alterações) para armazenar suas configurações.
O W3 Total Cache começará a fornecer seus recursos estáticos a partir do servidor CDN.
O W3 Total Cache também funciona bem com a CDN gratuita da Cloudflare. Como alternativa, você também pode usá-lo com o Sucuri, que é o melhor serviço de firewall de site com serviço de CDN integrado.
Solução de problemas com o W3 Total Cache
Depois que você configurar o W3 Total Cache corretamente, ele deverá funcionar perfeitamente em segundo plano para melhorar a velocidade do WordPress e aumentar o desempenho.
Ocasionalmente, você pode se deparar com problemas em que não vê as alterações feitas em seu site imediatamente ou um plug-in pode não estar funcionando corretamente.
O motivo mais comum para esses problemas é que você provavelmente está vendo uma versão antiga em cache do seu site.
Isso pode ser facilmente corrigido limpando o cache no WordPress.
Basta clicar no menu Performance (Desempenho) na parte superior e selecionar a opção Purge All Caches (Limpar todos os caches). O W3 Total Cache limpará todo o conteúdo armazenado em cache em seu site.
Se ainda estiver vendo a versão antiga do seu site, tente também limpar o cache do navegador.

I would recommend everyone to make a note of the changes you have made, especially. Issues on the website may not manifest immediately. For instance, it happened to me that after a week, WordPress started behaving strangely, and it was happening randomly. It took me quite a while to find the problem in the cache plugin and incorrect settings. If I had documented the changes I made, I would have found the problem more easily. It’s a recommendation for everyone.

Hello,
I’ve a question:

The free version of plugins will not slow down your site, poorly coded plugins can slow down your site.

Thanks for the great article! I really benefitted from it and have a better performance now 1/4 load time. One thing you should mention is in the Browser Page under Performance tab there is a box at the bottom that says Rewrite URL. Don’t check that it ruined my pages. All links were alterred but I took it off and it’s ok.

Hi, As per your recommendation, I have decided to go for MaxCDN, Is there any new update about CDN? Going to the MaxCDN site, there are different service including Content Delivery Network, Edge Delivery and other. Can your recommend me which service I have to select initially? I have new blog with no affiliate link till now and not planning for the next six month. And I am planning to apply Google adsense in the near future.Presently I installed WP Super Cache.
Do I need to switch W3 Total Cache to configure with MaxCDN? if I can configure MaxCDN with WP Super Cache, do you have any guideline?

I am Using W3 Total cache plugin for WordPress. My post has one table which updates every minute/hour. But as I do caching, the server does not serves latest version, instead it displays cached copy to the visitor. How can I purge cache every 30 minutes automatically so that it shows latest version of the post at after every 30 minutes?
I have already tried inserting this code in functions.php file but its not purging cache every 1h, instead it dies 2-3h later.
function w3_flush_cache( ) {
$w3_plugin_totalcache->flush_all();
}
// Schedule Cron Job Event
function w3tc_cache_flush() {
if ( ! wp_next_scheduled( ‘w3_flush_cache’ ) ) {
wp_schedule_event( current_time( ‘timestamp’ ), ‘hourly’, ‘w3_flush_cache’ );
}
}
Anna says
Thanks for such an easy to follow article. I broke my website yesterday using instructions from another blog. I should have come here first!!
I am a bit surprised by my results though. I did a Pingdom and GT Metrics test before I made all these changes and my page load time was:
Pingdom: 8.91 secs and GT Metrix: 5.3 secs
After I made all the changes I re-ran the tests:
Pingdom: 9.51 secs and GT Metrix: 9.9 secs
I thought my load times were meant to get much better – not worse!!?? What have I done wrong?
WPBeginner Support says
Hi Anna,
Allow the plugin to generate cache and recheck your scores. If that doesn’t help try to review your cache settings to make sure everything is setup properly. Alternately, you can try WP Super Cache and see if it helps.

Thank you for so great content.
Should I enable “Page cache” option in the process of development of site or only at when I launch it?
For me it is convenient to do this right now, but I think maybe during development it is not good as I visiting thousand times to check the progress.
WPBeginner Support says
Hi Roman,
Yes, you are right. You can set up the plugin later once your website is live.

Hi! Trying to install the W3 Total Cache Plug In, and while it says it is compatible with my version of WordPress, it says that the plug in is unavailable and says “Not allowed on our system due to performance, security or compatibility concerns. Please contact support with any questions.”
First of all… do you know why this is no longer working? And, do you have an alternative cache plug in that you recommend? Thank you!
WPBeginner Support says
Hi Jessica,
This means that your WordPress hosting company doesn’t allow the plugin. Most probably because they have their own caching solution integrated into your hosting account which doesn’t work well with W3 total Cache. Please contact your hosting provider for more details.

Andy Sellers says
Hi, I need some help please.
I’ve followed the instructions to serve my static files through CDN (and they’re very clear, thank you) and have found the process straightforward so far- but when I log in to my site the URL still starts with ‘www.’ and not ‘cdn’ so I guess cdn is not operational yet.
One thing I notice is that in the MAXcdn account page there is no option to ‘Update’ the Custom Domain settings as mentioned in the instructions – is this OK? I assume it now updates automatically?
But my main problem is that, assuming I now have to do this, I don’t know how to specify the static files in the custom files list in the custom setting of W3Total Cache. Help please. How should I fill in this Advanced panel – it’s now getting a bit too techie for me? Thank you.
WPBeginner Support says
Hi Andy,
You will login to your WordPress site using the normal URL. CDN only serves static files via their network not the whole website.
MaxCDN settings may have changed, but you would still need to setup your domain. Please contact their support and they will be able to guide you.

Derek C says
Thank you so much! I was about to go pay an extra $15 a month for cloud based hosting because my blog had gotten so slow at times it was unbearable! I had setup W3 Total Cache and just enabled everything.
I didn’t recognize it until going through your guide, but this was the main reason my dashboard and WP console was taking FOREVER to do anything. Sometimes I would wait 20-30 seconds just to create or save a post. Now it is like 2-3 seconds at the max. Also, my site loads even faster with a lot of that junk turned off.
I am on a shared hosting plan, and I guess all of the caching was actually bottlenecking the CPU or something…. Anyhow, thanks for such a useful guide!

Each time I test in pingdom the % faster than other sites decreases.

Ian Smith says
I recently set up W3 Total Cache with the Rackspace Cloud Files CDN. It all works, but I had expected the media files in the wp-content/uploads folder to only be posted in the CDN rather than on the server. Instead, media uploads now go to both the CDN AND the wp-content/uploads folder. Is this what is supposed to happen? It seemed unnecessarily redundant to me.
WPBeginner Support says
Yes, but the images on your server are stored so that you can end using CDN service anytime you want, or move to another service, or to create backup using WordPress backup plugins. However, your visitors will be served images from the closest CDN server instead of your site.

Hi ! I installed yesterday Super Cache because it seemed easier to configure than W3 Total Cache but this morning my site was very very very slow… So I decided to follow your tutorial step by step and change plugins.
So, the first step was to deactivate the first plugin, so I clicked deactivate Super Cache and my whole site crashed !!! I get this message : 503 SERVICE UNAVAILABLE no server is available to handle this request.
I don’t know what to do. Can you help ?

Thank your this tutorial. I have used it for a couple of my sites.
One thing, which might be a “duh” situation… But, I had my site in “Maintenance Mode” using SeedProd’s Coming Soon Pro. I did not see the CDN in front of the image urls until I turned off maintenance mode. Then, when I turned it back on again, they were gone again.
Just in case someone needs this information

Hello,
I appreciate so much, your posts. They have helped me learn a bit about setting up my website. However, this particular post led me to check a bunch of boxes under”Performance » Browser Cache” that took me from faster than 91% down to faster than 71% on speed. I had checked them just as you have in your picture above. I unchecked all your suggested boxes and got back to 84%. (on Pingdom) This was the only change I made. I don’t understand why it made things slower, or why I couldn’t get back to my original speed. If you could explain this I would appreciate it. Thanks.
WPBeginner Support says
A lot of reasons can show you conflicting results when you are expecting something different. For example, you may have forgotten to save plugin settings, your server is particularly under heavy traffic at that time. Make sure you enable gzip compression as we have shown above, then test.

How are you checking your website speed and performance? We recommend testing with pingdom using different locations. If it is still slow, then try resetting the plugin and follow the setup instructions again.

yes using pingdom to test and speed is 2.55s…I think we can do better

THANK YOU FOR MAKING THIS! I’m EXTREMELY cautions on the plugins I install from horror stories. I’ve also heard horror stories about this very plug in. Therefore, I research as much as I can: tutorials, forums, reviews, troubleshooting etc. I am going to follow your tutorial exactly. My server says my site is too large, 500kb, and needs to be gzipped. [sigh] Another plugin to search.
Helpful note: You may have a downloadable instructions on your site somewhere & I am not see it. But It would be helpful if I could download to print OR this was print friendly. you have have link but I am not seeing it.

Hi,
I do have one question, when static pages are created for example you have 200 pages and just installed and set up W3 cache. So now when static pages will be created for all those 200 sites.
Do you have to load it manually every site by site in your browser ? I understand that this action takes some time so when exactly those sites are created ( static copies on a disk) ?
