Re: NIST-SIP 55 CAPS on my laptop and counting!

I get 52 cps on my P4 2.8Ghz w/ Hyperthreading when I set #threads=1 or 
#threads=2
I tried tweaking the JVM options but this gives worse results 
(e.g. -server). This could be due to the relatively small

When I set #dialogs=10000, after a while I get (with 1GB of memory)

[java] Exception in thread "UDPMessageProcessorThread" 
java.lang.OutOfMemoryError: Java heap space

or, when I try tweaking the JVM options again,
