JMS publish rate is slow in SunOS

Question

I have a application that uses JMS as messaging system.

If publisher, subscriber and weblogic server is on Linux, publish rate is good enough(>30 messages/second).

But if all the three are on SunOS, publish rate comes down to 2-3 messages/second.

I tried to search internet but had no luck.

Is there any know issue about that? What can be the reason of this strange behavior.

Answer 1

I found where the issue was in logs :

Unable to load performance pack. Using Java I/O instead. Please ensure that a native performance library is in:

Weblogic has his problem on SunOS, when 32-bit machine has 64-bin weblogic or vice versa.

Changing mode of weblogic resolved the issue.

Still to understand what is this performance pack.
