Web Start App Runs Extremely Slow
We have had a very perplexing performance issue crop up with Java Web Start. When our application is run in the Netbeans IDE development environment, all the operations run at the normal, reasonable speed that we have come to expect from past experience developing this particular Web Start Application - both in the development environment and as installed through the Web Start deployment mechanism.
For the latest builds however, when the application is packaged and deployed with Web Start, it's performance is vastly degraded compared with how it runs in the Netbeans IDE - it runs approx. 20+ times slower! This includes ALL operations - this does NOT appear to be a loading/initialization problem.
We have just began trying to investigate the problem through run-time profiling, etc., but have not found the answer. If anyone has any insight into this problem - maybe, hopefully, have directly experienced the same problem - or has advise on the best strategy for diagnosing it, we would be very grateful.

We are facing the exact problem with a project build in java 1.5. We have 3 client machines, two of them run the application with jre1.6.0_33 and one with jre1.6.0_34. The strange thing is that only one machine running with jre1.6.0_33 is able to run the application as fast as it was an executable, the other two machines need also about 20 times more time. It is really frustrating to see how much CPU is left unused...
The reason why I mention all java versions involved is that I was convinced that java versions had something to do with it, but now I'm totally lost.
Hope someone has an idea...

We solved our problem by building the project with maven in stead of using eclipse to build it. Now the project runs smooth on all machines.
