  • Enable Page, Object and Database caching with W3 Total cache in one click.
  • Page Caching stores full copies of pages on the disk so that php code and database queries can be skipped by the web server.
  • Object Caching stores commonly used elements such as menus / widgets and forms on disk or in memory to speed up page rendering.
  • Database cache stores copies of common database queries on disk or in memcory to speed up page rendering.

Minifica le pagine HTML:

In che modo A2 Optimized rende più veloce il mio sito

La cache è il metodo più semplice e veloce per velocizzare un sito web dinamico.
A2 Optimized installerà e configurerà W3 Total Cache con il click di pochi pulsanti.

A2 Optimized rende più veloci tutti i siti

A2 Optimized renderà più veloci la maggior parte dei siti; comunque, non tutti i plugin sono compatibili con W3 Total Cache.

If your site is slower after enabling caching in A2 Optimized, talk to a developer about finding better solutions for the plugins that you are using.

Posso usare A2 Optimized con WordFence

A2 Optimized è compatibile con la maggior parte delle funzionalità di WordFence, comunque dovreste disattivare la cache e i log in WordFence.

Perché usare W3 Total Cache invece di WP Super Cache

W3 Total Cache è l’unico plugin che gestisce tutti i tipi di caching. Esegue la cache di query del database, oggetti e pagine usati di frequente. Inoltre permette l’uso dell’estensione Memcached come motore di storage per la cache.

Posso usare A2 Optimized su qualsiasi host

Si. A2 Optimized funziona su qualsiasi host che supporta WordPress; comunque, A2 Hosting fornisce alcuni strumenti in più per velocizzare il tuo sito se è ospitato su un server A2 Hosting.

A2 is horrible when it comes to supporting this garbage plugin. It's only an upsell for the "optimized" service. plugin broke my site with "header already sent" errors.

This plugin broke our CiviCRM cron script as well as a mailing list subscribe widget. It may have made a minor improvement to our desktop load time but had a negative effect on our mobile load time per Google PageSpeed Insights.

Thank you for your plugin. Didn't have any problem so far. Everything work as described in listing.

First, they did a bait and switch on their hosting pricing. Their advertised monthly plan did not disclose the price was actually for a paid yearly plan. That is false advertising. Next, if you signup for their hosting while using VPN, they will put your account on hold and ask you to send a scanned copy of your credit card and your drivers license or other photo ID. I've had an easier time getting through airport security. Then when you install the plugin, if you do not have your hosting with them, the plugin will subject you to heavy-handed advertising reminding you that the plugin is best used with their hosting. But even if you do have A2 hosting, the plugin will either crash your site or cause conflicts with other plugins. That was the last straw for me. I canceled my hosting plan and got my money back. At least that was hassle free. No doubt they have a lot of experience with issuing refunds.

I thought because A2hosting is such a good host it's Word Press optimization plug-in would make my Word Press site even better. I've had this thing installed on my sites for more than a year. It's interfered with other plug-ins most notably WordFence. It has also sometimes interfered with the update of my Elegant Themes, Divi theme. I've had to disable this plug-in before the update would become available. Recently I've discovered it has been slowing down my sites and the reason I've had no comments on any of my posts the last few months is that it requests completion of a captcha, but doesn't supply any captcha to complete. I've deleted the thing. A2hosting should be ashamed.

After experiencing the great service A2 Hosting provides, I heard about their plugin and assumed it would be of similar quality. I was using WP Super Cache so I uninstalled that and installed this plugin as well as their W3 Total Cache "optimized" plugin. Using this instead of WP Super Cache, my CPU usage was down slightly but my physical memory usage and IO usage spiked very high, to the point of causing faults on my A2 shared hosting plan. Page load times went significantly higher, on the range of 2-3 times higher. Uninstalled and went back to WP Super Cache. Given the quality of A2 Hosting, this plugin was a huge disappointment.
