Server Optimization Request (VPS)

محروم.كوم · #1 08-07-2009, 11:40 PM

1. VPS with 896MB of RAM (I'll request an upgrade to 1GB in a few days). 18 other VPSs hosted on the server.

2. Server Specs:

CPU Speed/Type: AMD Quad-Core Opteron 2350 2GHz (I see 8 CPUs in total, maybe using something like "hyper threading").
Memory Installed: 16GB
Hard Drive Type/Configuration: SATA-2 HDDs in RAID-10 array managed by the hardware RAID controller
Linux Distributor: CentOS release 5.3 (Final)
Apache/2.2.11 (Unix) | PHP 5.2.9 (cli) + xCache 1.2.2 | MySQL 5.0.81-community

3. vBulletin 3.8.3

4. No.

5. MySQL was installed by cPanel from the RPMs.
