Minimum hardware configuration for running Java

Morris Makuch — Fri, 26 Mar 2004 10:10:21 GMT

Hello. I am having a problem running java 1.3.1 on a rp2470 single 650MHz processor and 1GB memory. It is brutually slow. And brutually is putting it mildly. I have run the HPjconfig utility and applied all required patches and kernel paramters suggested by the utility and still it is joke. Is a rp2470 with 1GB of memory sufficient or is it just not enough horsepower to run java applications? Thanks

Your server is certainly powerful enough.

I run that version of java on a D320 with a 120 Megahertz processer(i think on the speed) and 750 MB of RAM.

So what you have is a performance problem.

I suggest you patch your system to the latest Gold Pack and collect some performance data and deal with the bottleneck.

I'm attaching a script, but would suggest you start with shared memory resources and networking.

Hi

www.hp.com/go/java

run HPJmeter and Jtune (Very useful)

Do you get errors in syslog.log

HP-UX PA-RISC systems: Users will get the best performance with HP server series rp5400, rp7400, rp8400, and Superdome, and PA-based workstations. The recommended minimum system for running Java applications is a PA-RISC 2.0 system.

You have 1.3.1.?

Morris,

Is it a Java GUI that's having the
performance issue? There is the infamous
remote display issue introduced in
the 1.3 timeframe. Specifically,
if you set a DISPLAY to a remote machine
the performance will be awful....
This supposed to be fixed/made better
in 1.4.x. Again, this would only apply
to Java GUI apps displaying remotely.
