I've been messing around with the net.inet.tcp.sendspace and net.inet.tcp.recvspace parameters on ftp.freesoftware.com and have found that there is a significant performance improvement when increasing these to 32768 bytes. Apparantly there are enough systems out there with higher window maxes that it really does make a difference. By significant improvement, I mean about a average of a 20% increase in Mbps per user, and this was just the change over a 30 minute period with lots of connections still using the old 16K values. Any objections to increasing the defaults in FreeBSD to 32K? -DG David Greenman Co-founder, The FreeBSD Project - http://www.freebsd.org President, TeraSolutions, Inc. - http://www.terasolutions.com Pave the road of life with opportunities.
