There are certain RealTek chipsets that perform very badly in both Windows and FreeBSD in my experience. This is due to poor hardware design as far as the FreeBSD driver author could see. Replace your network card with a $30 PCI 10/100 card that is not a RealTek such as the VIA Technologies VT3043 `Rhine I' and VT86C100A `Rhine II' chips and you'll get much better performance (FreeBSD 'vr' driver). Search the cvs-all mailing list archives for mail re: the 'rl' driver. In my experience: A no-one could get files from a firend of mine's Windows 95 box but he copy them to other peoples machines. If you did manage to get a small file it was corrupt. Under FreeBSD we had the same lockups you are having (using UTP). If we used coax (BNC) it worked fine. This was all at 10 Mbps. We didn't test Windows on coax. Now that we have put a Rhine based card in his machine both Windows and FreeBSD are working fine at ~1 MB/s through put (at 10 Mbps) and NFS is working fine.
