Hi sanit,
I got some benchmarks from our last working VZ board...
mmh.. seems the CPU is clocked at 17MHz... I don't know if this show the
real clocking of it or if it's an error...
The pgserver is a bit old and then the benchmarks aren't the same as yours
I even don't remember their signification...
Maybe Micah could help about this?

Results are measured in frames per second. Complete includes
screen hardware updates, raw is just the software. Raw should
equal complete if the driver does not double-buffer
