Hello,

Is there anyone having performance benchmark when apache is
running with and without SSL on the same software and hardware environment and serve mostly php pages?

I'd like to know how much will the performance be effected when I
move everything from apache to apache-ssl.

Any URL, experience and ideas are highly welcome.

I think you can compile apache with buildin ssl support, then you get an ab (apache bench) binary that supports https

that should be all you need

Loading the apache module itself doesn't add much to the load. The real question is how may user, traffic, and sessions are you planning on running through it.

IIRC ssl negotiation is a fairly heavy transaction, but ssl data after that is pretty light. You may want to load images from a non ssl page, etc. If you're planning on serving more that 200 concurrent sessions through SSL you will see a noticeable degregation in service.
