Here is my set-up currently.
Intel Pentium 4 and 6 gigs of memory with some old scsi drives.
Adjustment after adjustments I finally worked out most of the bugs.
Blank admin page after upgrading to APC 3.1.3p1
The fix is to disable apc.include_once_override = 0 or just removing that line altogether.
I guess its time to give some support back because W3 Total Cache saved my WordPress site and server from a total collapse. Now, I have the time to move my WordPress to a powerful server, add some memcached servers and keep using this plugin.
I had a few bugs that took a little time to hash out but overall definitely worth the time.
