Subject [users@httpd] Win32 Apahce 2.0.55 and mod_ssl
Date Mon, 30 Jan 2006 17:46:47 GMT
I'm benchmarking one of our sites. After some debugging I have found
that when the site has ssl enabled, performance starts to degrade very
rapidly, even to the point of rendering the server useless after 20
concurrent users.  The servers CPU resources are 2% at this point when
Apache fails.  So it's not a hardware limitation. The Same tests yields
very good results without SSL

Server: Win2k3
Apache: 2.0.55 + mod_ssl
Hardware: Dual CPU machine. 2 gigs ram.

Apache uses about 150megs ram at most.

The httpd.conf is default for the most part.

The application is an Apache::ASP (perl) based application

Are there any SSL tricks and tweeks that I can do?
