Does anyone here (other than me) use JRockit JVM too? I found it's 1.5x faster to start JBoss but very slow for swing apps... I'm not sure if I should switch to it now, please give me suggestions/comments!
Seems pretty obvious - if, in your experience, it's slower for Swing apps, and you mainly use Swing apps, then don't touch it!
Perhaps it's a matter of picking the right tool for the job. JRockit may be better for j2ee systems, in which case utilise its strengths. For Swing apps, just use the standard jvm from Sun.
