Benchmark for RackVM VPS

Originally posted on May 24, 2010 and imported from my old WordPress blog.

The following is the benchmark results from my ~$2/mo VPS at RackVM. The VPS is XEN based with 128MB RAM. For such a good price, it was hard for me to resist giving it a try. I’m surprised that the service is fairly decent, although the disk does sometimes lag. But for my requirements, the VPS is well worth it.

Hypervisor	XEN-PV
Memory	128 MB
