The 3com 3c905 is not a very good card under FreeBSD the driver was
written
without support from 3com and is shakey on a lot of hardware.  I would
say
there's a big question that your server is actually saturating the
ethernet.
Probably that is why your only getting 90Mbt.

Once again, the winxp+realtek 8139 is not a particularly steller combo,
I would question that this system could saturate the ethernet, either.

OK, next question:

ftp transfer like this uses large packets, rerun the test with ping -f
with different ping packet sizes, post the results.

Remember, routers have to deal with many sized packets.
