X-BeenThere: freebsd-performance@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list Reply-To: Bill List-Id: Performance/tuning List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 13 Feb 2004 00:21:28 -0000 What steps would I need to take in order to obtain 75,000 concurrent TCP sessions on a FreeBSD 5.2 system running on the following hardware: dual xenon 3ghz 1mb cache processors 2 gigs of memory two dual port fibre gigabit nic's 1 onboard copper 10/100 nic I read a post that was sent to freebsd-hackers, which mentioned an individual was able to obtain 1.6 million concurrent tcp sessions, so I assume it's possible. My goal is to setup a server, which is capable of accepting at least 75k tcp connections to perform some firewall stress tests at work. Given that information on this subject is quite scarce, I thought I'd post this question and see what type of response I get back. Any assistance or suggestions would be greatly appreciated, Thanks in advance, -=-Bill-=-
