My blog was running Apache with APC and I've switched to W3 to take advantage of the minify options. After some testing I found the best results were using disk cache for page minify, and object caching. Database caching is disabled.
Does APC have any purpose in this setup or can I uninstall it? I'm on a VPS with only 512MB so would rather not keep it loaded if it's not being used. There isn't anything else hosted on the VPS besides my blog.
