 * Hi all,
 * I’m wondering if someone can help me out. I have 35-40 wordpress sites that are
   running all under the same server. We’ve been having some crashing issues because
   of CPU overload. We have about 1000 PHP cron scripts that run and use XML-RPC
   to generate new posts.
 * Our hosting service recommended W3 Total Cache and we’ve implemented it onto 
   all of our sites. However, I’m not seeing benefits to the server crashing issue.
   I’m guessing that this is because of the cache being emptied every time that 
   there are new creations (edit, new post etc).
 * Would it be even worth using w3 total cache? I’m seeing a lot of CPU usage on
   index.php and my guess is that it is because of new caches being created. Can
   someone verify if this is true? Maybe it’s better not to cache it since all pages
   are changing so frequently.
 * I have a dedicated system with (4 cores) and 4gb of ram. Memory usage typically
   does not go above 35% but the 4 cores goes up to as high as 11 and then drops
   back down. I think that is when the caches are being generated. I was monitoring
   traffic and there was only 1 visitor on the site at the time.
 * Any input is GREATLY appreciated!

 * Anyone have any ideas on this? CPU usage is up the roof and can’t seem to figure
   it out. I turned off W3 Total Cache and it seems to be okay…but I suspended 3
   other cpanel accounts…it’s hard to say what the right fix is for this =/

 * I would have to look at your server to see how W3TC can be tuned for your system.
   Please send us an email.
