What hardwre are you using for the client and the server? are you running ab from localhost? What options are you using with ab? Most of the CPU cycles in each transaction are going to be spent in the SSL handshake. I just did a quick test of one of my servers running 1.3.37 on a dual Xeon 3.06, using a P4-3.2 as the client, and saw about 5000rps for HTTP, and 24 for HTTPS. I suspect that the latter may represent the capabilities of my client machine rather than the server machine. If you want fast SSL, you need hardware acceleration.

I am currently running the following software Server Version: Apache/1.3.37 (Unix) PHP/5.1.6 with Suhosin-Patch mod_ssl/2.8.28 OpenSSL/0.9.7e-p1 All built from ports. In testing of the web application I noticed that once SSL was added the initial login to the site was slowing down. I did some testing using Apache Bench and have noticed that without SSL the server can process about 700 requests per second. Using SSL the number is in the 13-15 range. I have tried changing a few parameters (log level, SSLRandomSeed, SSLSessionCache) and have seen 0 improvement. Using server_status shows that there are plenty of resources available. Any help would be appreciated. Tim
