Been using WP Super Cache for a couple years. Doing some updates and decided to give W3 Total a shot,
Let me preface this review with the observation that each wp site is different, and there are no absolutes as to what works and what doesn't work.
After installing Total Cache and activating, the admin and frontend of the site went into 504 timeout. The only way I was able to get back into the site was by deleting Total Cache via FTP.
I then discovered that there were literally thousands of files created by Total Cache. I was able to delete this rather quickly via the file manager in my cpanel...the point is the huge amount of files this plugin created...Never seen anything like this before.
It took me about 2 hours to get rid of this plugin, it's files and all the settings, and clean up the htaccess files and config files. Even then, to get everything working properly (kept getting server maintenance messages, which I have never seen before)..I ended up having to reboot the server and mysql dbs and flush as needed.
Not a good experience. Obviously there are a lot of people that are having a good experience here...just a word of caution before you jump into using this plugin. WP Super Cache is back in place on my server...and if you want something that you can install and configure in 10-15 minutes, the WP Super Cache is a good starting point.
