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?
