SSL proxy slow....

[James]

Here is my server config.  When I go to http://prod.givvy.com  the  
result is normal.  When I go to https://prod.givvy.com it's dog slow.

Any idea as to how to speed up the SSL side of it?  (right now I am  
using a local host change to point to the right IP address as  
prod.givvy.com points to a maintenance page.  We want to launch the  
site tomorrow, but this is a huge problem for us.  I'd hate to launch  
it with one server.

Thanks
James
