One of the things to check for on a poorly performing Ethernet connection
is a duplex mismatch, especially with Windows involved. The drivers
commonly autonegotiate a full-duplex link but really only run at
half-duplex. That WILL tank the performance. You say it is 100baseT, not
100baseTX (switched). Maybe try forcing the Windows NIC to half-duplex.
If your network gear is sufficiently sophisticated to be able to show
errors on the ports check to see if your getting collisions on a
full-duplex link or some other wierdness.
