WebStart Performance issue

Hi all,
Now I am in the trouble of webstart. I developed am application which client side is written by swing (server side is EJB). I debug it on my machine and running performance is ok, but when I depoly it by webstart. The speed will be slower 2~3 times than runnig on my machine. What's wrong with it? Is there any special place I need to care or config?
I will thanks a lot if you can help me!
Thanks
Qing

Hi Qing,
I had the same problem some days ago ...
I found a hint about WebStart performance and the SecurityManager,
so I signed my application to avoid those constant security checks.
Then it was as fast as started as JAR !!
You can try it locally using a test certificate, see Howto by SUN
I hope this will solve your problem ...
