Dear all,

I have a very basic question,

My WAS 6.1 server is running in under jdk1.5. My ( EAR)deployment build path is pointing to jdk1.5. Everyday i take the latest code build fromjdk5 and deployed in WAS 6. Its is working fine. Now I have changed the EAR build path version jdk6, and also I made the build also jdk6, and deployed WAS6 which is pointing to jdk1.5 . Now I am getting performance issues in WAS 6.

Is it related to jdk version or deployment issues?

Thanks,
SR

I dont think you can blame JDK or WebSphere version for performance issues. What do you mean by performance issues?

Java is based on a Virtual Machine architecture, JVM, based on a byte-code interpreter. Performance of Java systems can vary considerably based on how the VM is implemented. For example the performance of the JVM for JDK 1.1.2 was double that of JDK 1.0.2. "Just in time" compilers (JIT) for Java can be considerably faster than a byte-code interpreted version. Even if you plan to use a JIT, it is important to understand the JVM, to get an understanding of relative costs of operations.

In my was6 is running under JVM1.5. My code compiled in JDK1.6. So that i am asking that question.

Thanks,
SR

I'm sorry, for a moment I thought that was supposed to be an answer to the question. But then I noticed that you were the one who asked the question in the first place.

So you should answer the question you were asked...
