Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hi, Fund a URL for TCP tuning at http://www.csm.ornl.gov/~dunigan/net100/auto.html At the bottom of the page, it says: OpenBSD/FreeBSD saved ssthresh/cwnd info for a path in the kernel routing table, as I recall? That info could be used to "prime" subsequent connections on the same path. Reference ? I traced the tcp_input.c/tcp_output.c (4.3-RELEASE), and did not found such information. Would someone confirm above information or point to where is the code or document for saving this ssthresh/cwnd information to the routing table?
