I'm getting a new server with 12GB ram. It will run several large vbulletin forums (one at 2.5Mil posts) w/vbseo, a classifieds script, and some static websites. We use XCACHE php accelerator (which I understand does work in 64 bit). The server does a bit of everything (email, web, mysql, php, etc), but all sites are controlled by me and we don't allow access to cpanel/whm to anyone but me.
Question: Is Cpanel finally ready for a 64bit OS? I will likely have CentOs 5 installed. I have been told by more than one datacenter that they recommend 32bit with PAE kernel for Cpanel w/12GB support. They claim that is more stable. I know there have been 64bit problems with Cpanel and/or updates in the past, but I *thought* those had been worked out. Can I get an official response here or one from people with actual experience?
From what I understand, the limits of PAE kernel are some performance penalties for memory mapping (in addition to the 32bit vs 64 bit one), and programs can only each access 4GB at a time.. That's not a huge deal for most things, but it might be nice to have the option of allocating more than 4GB to mysql.
Thank you!
