We're considering buying a dual processor machine to run our java
programs but if we can't get something running with a jdk on an smp
kernel there probably won't be much point.
Only reasonable results I got were with no jit (java -Djava.compiler=none etc.). For our testing (JMS environment) we got better throughput on 2 CPU SMP server with no jit than on non-SMP w/jit.
I did see on the JDK 1.3 Linux beta readme that "Sun does support or recommend running the Java 2 SDK on SMP kernels."
Can anyone from Sun / Blackdown comment on future SMP support, and what the underlying issues are?
