Linux Performance and JVM (using Sun jdk 1.4.1_01)

"When the system is configured to run on a ONE CPU machine, the system throughput is roughly 74,000 msg/second. When the system is configured to run on a 2 CPU machine, the system throughput is roughly 27,000 msg/second.

The data source and ‘another process’ are running on different machines and they are consuming very little CPU. They have be ruled out as having any type of a performance problem so the data is available for the main application to consume.

We had the same issue when running the application on a multiple CPU Solaris box. We added the following VM arg:
-XX:-UseLWPSynchronization
And added /usr/lib/lwp to the LD_LIBRARY_PATH environment variable. The throughput of the system increase 2 to 3 times when these options were used." (-- submitted by a user/developer)

We are having performance issues regarding JVM on a dual processor (1.4Ghz Dell PowerEdge machine) comparing to a single processor same Dell box that performs better.

Has anybody experienced such performance issue? We are using Sun JDk 1.4.1_01 on both boxes.

Any ideas how to remedy this problem?

Thanks.
