I believe I found the best fix for the problem. Even with setting tcp_deferred_ack_interval to 1 it was still slow. I set that parameter back to 100 and set tcp_deferred_acks_max to 0 (disabling deferred acks basically) and suddenly things were as fast as they could be. (Faster than any of my previous times when I was adjusting rsize) Again, there may be some other problem with windowing and such, but this fix is certainly easier than trying to track the windowing problem down. (Especially since I was never having good luck there) Jaime To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
