I have an httpd v2.0.45 webserver that insists on blocking for 9 seconds before serving a static page. This delay happens both with a normal http site, and an https site. Hostnamelookups are switched off in the config, is there anything else I should be looking for besides DNS that would cause the webserver to not return the page straight away?
It'd be helpful if you said which MPM you were using. Each MPM has different performance characteristics.
You should run strace (or truss) on the httpd and see where the hang is. In order to get one process, run 'httpd -X' if you use prefork; worker respects -X but in a different manner - one process with many threads - not as helpful as prefork in ONE_PROCESS/NO_DETACH mode.
Aren't you using mod_auth_ldap? Couldn't it be blocking on LDAP? -- justin
