After much to-ing & fro-ing ealier this year, I ended up using a Realtek on an otherwise respectable machine. For the most part it seemed alright. Then just before I went on an extended overseas trip 7 weeks ago, it started doing odd things. Small transfers worked OK, but larger ones just trickled through. The effect was immediately observable with tcpblast. Once you sent a number of 1k blocks that was over the tcp_sendspace & tcp_recvspace limits, the transfer rate dropped dramatically. Adjusting the tcp_sendspace etc parameters affected when this would happen. UDP seemed quite happy (thank goodness for that, as otherwise NFS would've gone down the drain) Anyway, there were NetGear cards going cheap, so I replaced the Realtek with that and all is well.
