So is there hope for better Java-based SSL performance with 1.5? I've tried using JMeter for some quick performance testing. Works great for non-SSL but SSL is dog-slow for even a couple of user threads on a reasonably fast box.
We haven't done any performance measurements on the 1.5 SSL API yet, but the old I/O library should be faster than that for SSL. Typically SSL performance is 1/2 to 1/3 of the performance of non-SSL in our application:
Here's some numbers: http://www.webperformanceinc.com/webstresstest/performancestress.html
We ran two tests, identical except that one was SSL and one was not.
The same page also shows some interesting differences between the Sun 1.4 JVM on Windows and Linux on multiprocessor hardware. Our test application run on Windows 2000 Server with 2 CPU, 800 MHz hardware will generate 1002 hits/sec, while the same test on identical hardware on RedHat will generate 2755 hits/sec.
