I've got a ping time of around 100us (ranges from 0.093ms to 0.109ms)
So from your formula I should be able to saturate 1 gigabit ether.
I was getting around 90 meg/sevond using ggate
Am going to experiment now with the recompiled hastd using
the buffesr sizes I was using with ggate and see what happens.
thanks,
