I've read probably every thread on this plugin and can't seem to find a confident answer. We're looking to optimize our caching so we found W3 would be the best after reading dozens of reviews and getting a personal recommendation from our hosting company.
In regards to the type of caching (disk vs. APC), we're wondering what the best method to do it is.
Quad Core machine
4 GB Ram
Our hosting company suggested that we try APC, so they enabled it leading to several error messages of "warning: unable to allocate memory for pool apc cache" or something like that. They increased the memory to 512mb and it seems to be working fine now.
The suggestions that I was best able to find were the following:
Page: Disk enhanced
Would these be an optimal setting for a system like mine? Should I increase the APC memory usage even moreso? I'm not a linux or server guy, and work strictly in PHP/MySQL and Design. If someone, or possibly Frederick himself could provide some insight on this, I'd greatly appreciate it.
We have 37 sites running on the dedicated server, not much traffic as of yet, but rapidly growing. Thousands of cron scripts that are scheduled outside of wordpress and several uses of XML RPC.
That about sums it up. Any feedback would be greatly appreciated.
