Joshua, Thanks for you thoughts - I would have said the same thing. I forgot to mention that the max threads per child is set sufficiently high (200) to run 64 threads already :-( Plus, having max threads per child would not explain why apache takes several second (over 30) to recover and why no pages were served at all under that load. It would appear than opening 64 sockets at once to Apache just 'over whelms it'. This issue is definitely more pernicious than just max threads :-(( Thanks AJ Alexander J Turner Ph.D. www.deployview.com www.nerds-central.blogspot.com www.project-network.com -----Original Message----- From: jslive@xxxxxxxxx [mailto:jslive@xxxxxxxxx] On Behalf Of Joshua Slive Sent: 12 September 2006 19:36 To: users@xxxxxxxxxxxxxxxx Subject: TPN POSSIBLE SPAM:Re: [users@httpd] Windows max threads > > I am load testing apache 2.2.3 on windows XP. If I attempt to open 64 or more sockets, it stops serving for a time then recovers. I know this is not that the OS is running out of sockets etc because TAG.net handle 256 sockets simultaneously without any trouble. > You probably need to raise ThreadsPerChild: http://httpd.apache.org/docs/2.2/mod/mpm_common.html#threadsperchild Unlike the unix version, apache httpd for windows does not dynamically adjust to load. You need to specify in advance (using ThreadsPerChild) how many clients will be served.
