Slow network performance...

[confieldx]

I only receive transferrates around 2-8 Mb/s between computer A and B on my gigabit lan. Before we're going into details, any quick ideas/suggestions on what could be improved? I should also mention that Computer A is having a 100% CPU utilization whenever I access it "heavily" over the network (file copying, streaming videos, etc...) I've tried a few different NIC's in Computer A... same bad results....


Switch: Dlink DGS-1008D

Computer A (server)

Computer B (workstation)
===============
cpu: pentium 4 HT 3.0 @ 3.25 ghz
ram: 1024 mb dimm sdram pc3200

Thanks!

sounds like bad drivers? the slow b/w would be explained if the cpu was hitting %100 when reaching 8mb, and it shouldnt be maxing the cpu that fast unless there was some issue with the driver.
