Java 1.3 and a d-350

Brad Marks — Tue, 12 Feb 2002 01:00:31 GMT

I'm attempting to run an application written in Java on my d350 (single 100mz processor, 448mb memory). Running a VERY simple java script (prints 'hello' to screen) pins the CPU at 100%. And running the forementioned application software pins the CPU for an extended time.
I have installed all recommended patches and tuned kernel parameters, all to no avail.
I'm thinking that this system is too small -- at least cpu-wise -- do deal with the overhead that Java creates.
What say you guys?
In appreciation,
Brad

Brad,

What Release are you running, and if its 11.x, is it 32 or 64 bit?

Hi Brad,

It Could be the system is too small.... A D350
will only run a 32 bit operating system. Are
there any applications sharing the system?
Sometimes sharing a system can bring you
extremely bad news performance wise.

See the link which provides a chart to 32
and 64 bit Operating systems.

I'm running 11.0 and, of course, it is in 32-bit mode.
This is an R&D machine and there are no users' processes except me!

have you looked into HPjmeter?

Have you gone through these links?

personally, I have always disliked the D-class and R-class machines, and the K's aren't much better (I thought the 8080 was slow). Now as for the A-class, N-class, and rp8400's, they kick butt!

Thanks for that Harry; I'm looking at the RP5430 to replace my k-420 production machine.
I think I'm going to stop trying to force the d350 to do things that is was not designed to.

Thanks all for your continuing help,
Brad
