Thank you Bob for your help. The net.inet.tcp.rfc1323 was already enabled but the problem still exists. Upgrading is not an option as it is an underlying os for an appliance running Spam Filter software. -----Original Message----- From: Bob Middaugh [mailto:bob.middaugh@comcast.net]=20 Sent: Thursday, August 30, 2007 11:16 AM To: Shah, Baiju-p98993; freebsd-questions@freebsd.org Subject: Re: Question about Window Scaling Hi Baiju, Try this to get started: http://proj.sunet.se/E2E/tcptune.html http://www.wormulon.net/files/pub/FreeBSD_Network_Tuning_-_slides.pdf If upgrading is an option: http://caia.swin.edu.au/reports/070717B/CAIA-TR-070717B.pdf Hope that helps, Bob -------------- Original message ---------------------- From: "Shah, Baiju-p98993" <Baiju.Shah@gdc4s.com> > Greetings. >=20 > We currently use Espion appliance running FreeBSD 4.9 as a mail=20 > interceptor for SPAM.
