Unix Bench Results
This was taken on a 512 MB CentOS VPS that is identical to what we offer in our standard plan.
These benchmarks were taken on servers under average load from other customers, so they are realistic. Since we don't oversell our servers this level of performance is consistant and predictable.
Here is a benchmark from the WHT modified Byte Unix benchmarks:
