Java 1.3 Slow to start

Paul Remeika — Sun, 17 Apr 2005 07:40:54 GMT

I have installed Java jre 1.3 on HP-UX 11.00 and it is slow to start up when running my application. Can I tune the kernel to improve this?

Did you install all the required patches for java1.3 on your server?

Checklist:
1) Patches (prior post)
2) OS patches, March 2005 or December 2004
3) General performance review (is anything else slow, what is user response on non-java, is the box swapping).

I'm fairly sure java 1.3 os old & has had newer and faster siblings..
also make sure you run your java processes with the -server flag.

Other than the above, java tends to be slow to start, it is the nature of the beast. Various optimisations are going on, and this is generally refered to as "warming up".. If you have lots of short runing java processes, then java may not be the best tool. but if the java process runs for quite some time, then java has a fighting chance of delivering performance.
