glad it was caused by the cert and you were able to fix it. unless you stress the server, I doubt you'll see a difference. Many of the larger E-Commerce sites use bigIP or a SSL enabled router. The webserver only handles HTTP traffic and the router does all the encryption. I may have the old numbers Remy and I ran back in 2002. If I find them, i'll post it.
