Hi,

we have tool wihich is very nice with JDK1.4, if we compile the same code with JDK1.5 and run in JRE 1.5 , the performence is very bad.

I throught we will get more performence by using jdk1.5.

My application uses RMI and Swing.

kindly give u r valuable suggestions to improve the performence.

Thanks in Advance,
Rajesh Gannarapu

What do you meant by the performance was bad? What measurements did you used? Or rather, what did you came to that conclusion?

Which part of the system is being considered as performing badly? Is it the RMI component that you're saying that performance was bad? If so, it could be your network traffic.

Ideally, if you've access to tools that allow you to perform load tests on the system, you would be able to tell difference between the performance of the same system on 2 different JVMs.

If not, you make use of logs to give you the transaction times & compare betweem the 2 JVMs.

These would be more concrete.

Moving this to the Performance forum.
