Any thoughts about how to make them communicate more effectively? Personally, I don't think it's just window buffers. I think the whole darn TCP/IP stack misconfiguration plus maybe not perfect NIC drivers are the reason for underperformance. I know that most of the real "mistakes" must be on the Windows side, but that's not an excuse for FreeBSD/Linux to not be at least 99%-Windows-networking-compatible. Andrew P.
