How powerful is the machine you are running on? In general, you could see a significant decrease in performance when enabling SSL depending on the hardware. We did some load testing on a single CPU machine with SSL enabled and were getting poor performance (Apache was taking up about 80% of the CPU cycles). We off-loaded that to a dedicated hardware SSL Accelerator and saw a significant increase in performance. Unfortunately, I'm at home so I don't have the numbers with me.
But yes, your numbers are probably reflecting reality correctly as far as what I have seen in our testing. -Scott On 3/9/07, Patrick Berry <[EMAIL PROTECTED]> wrote:
Apologies in advance, I know this is a topic (SSL) this is greatly misunderstood and generates more than it's fair share of questions. We've never had a problem with CAS 2 performance, even though we run tomcat 5.0.28 with nothing in front on JDK 1.4.2. We foolishly never did any baseline performance testing with httperf. We finally ran into a problem and started to do some testing. It came down to this, just hitting /cas/login : SSL: 11 connection/sec No SSL: 150+ connections/sec Question: Is this basically what others see? I know the solutions, upgrade JVM, upgrade tomcat, upgrade CAS, cluster CAS, offload SSL and I'll get there eventually. I mainly just want to see if my tests reflect reality (not just my own reality).
