Question

Performance issue with admin java applications

Hello all,
Recently we moved our servers from solaris to redhat linux.
Since then all the java applications like windu, jconsole , profiler,
windchillDS control panel etc are running very slow. Refresh rate for these
applications is horribly slow to the point that they are unusable.
I am wondering if anyone ran into this issue. Any tips to debug this will
be helpful.

Thanks,
Prathap <">http://goo.gl/LuT5>

I'd suggest starting by ensuring that you're not accidentally running
them with OpenJDK -- as it's performance isn't as good as the Oracle
JDK, particularly for GUI operations.

Thanks for the pointer Jess. We are using the JDK that came with Windchill.

echo $JAVA_HOME
/opt/ptc/windchill91/Java


java -version
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode)


Thanks,

Update 14 is rather old. The current Java 6 Update is 30.

That said, I don't really have any idea why this is slow -- I wouldn't
really expect Update 30 to be hugely faster than Update 14.
