Rackpace.com Cloud Server – CentOS 5.5 64bit install and setup

Rackspace Cloud Server benchmarks

First I ran UnixBench 5.1.2 to compare the performance with my local Virtualbox server which consists of

• VirtualBox CentOS 5.5 64bit Guest
• Xeon W3540 @3408Mhz (Assigned 2 cores only) – linux reports @3375Mhz
• 16MB allocated GPU memory
• 1GB out of 6GB DDR3-1550Mhz
• 20GB out of 640GB Samsung SATAII

UnixBench 5.1.2 local Virtualbox server turns out to be at least 2.5x times faster than the Rackspace Cloud Server 4GB/160GB instance.
