Are you kidding? It appears that you have a) 2-3 times as much
memory in W2K machines, b) Much faster CPU's in W2K machines, and
c) much more recent software in W2K machine.
So, yes, I would expect different performance among the machines
<grin>
40Mbps may in fact be the maximum output for that machine. Don't know.
The only way to compare would be to now load W2K on that hardware, and
see if it also get's about 40 Mbps.
There are numerous things you can do to tune Linux, but it's not
clear that they are necessary at this point.
You're comparing apples and elephants, and trying to make judgements.
Won't work.
