In article <local.mail.freebsd-stable/200104051727.f35HRp324853@cwsys.cwsent.com> you write: >No need to reply.

TCP newreno is an algorithm for better recovery of lost packets, in the absence of a SACK implementation. newreno should improve performance during packet drops, not decrease it. I would be interested in seeing a tcpdump of the traffic, in order to see what is going wrong. Would it be possible to get a binary tcpdump (-w option) of the traffic stream on both machines? -- Jonathan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
