You might want to try: net.inet.tcp.sendspace=$((128*1024)) net.inet.tcp.inflight_min=$((64*1024)) net.inet.tcp.inflight_enable=1 Try to increase inflight_min if necessary. Of course this will effect all sending data to this box, so it might have other negative effects. > -----Original Message----- > From: Dan Nelson [mailto:dnelson@allantgroup.com] > Sent: Wednesday, July 09, 2003 1:21 PM > To: Max Clark > Cc: freebsd-hackers@freebsd.org > Subject: Re: What ever happened with this?
