Use WP Super Cache for WordPress speed, not W3 Total Cache
We keep coming across WordPress customer sites that have hurt their performance by switching from the “WP Super Cache” plugin we recommend to a newer plugin named “W3 Total Cache”. Unfortunately, their site often ends up being far slower after switching to W3 Total Cache.
If you care about the performance of your site, please stick with WP Super Cache unless you have a very good reason to switch. It works, and it works well.
Some people tell us that W3 Total Cache works just as well if it’s properly configured, and they may well be right — but it seems like it’s difficult to configure properly. Our experience is showing that it’s easy to get wrong, and performance ends up suffering. WP Super Cache makes it easy to get great performance.
