A question regarding CPU usage Orbeon

RdeBeijer
Hi,

I have a question regarding CPU usage when using Orbeon.

We have Orbeon running on Tomcat-6, and an XHTML file with approx 500
elements divided over several tabs, when I load the form I see the CPU
run up to 50%
and when loading the page 2 times parallel the CPU goes the 100%. Its
stays on 50 or 100% for 2 seconds. Is this because of the SAX parsing?

Is this CPU usage default Orbeon behaviuor? I am using Orbeon 3.6

Are there certain settings that I can tweak to adjust Orbeons CPU usage?

Regards Ramon

Hi Steve,

The settings we are using are:
-Xmx512m -Xms256m -XX:PermSize128m

We expiremented with these settings but it didnt show much improvement.

Regards Ramon
