Hi. 

I'm running the 1.4.2 server on windows/cygwin.

I'm trying to run a stress test of server. I have turned of Karma (inc/dedc
= 0) and <rate Points is set to 100, time=1. 

I have also made a server side component to offload the JSM. All messages
are sent direclty to the server side component. 

The clients are very simple: connect and send a message on a spesified
timer. 

The test where done several times and the same occured every time!

1) Test one:
One message pr second:
	When i reach 45-50 clients jabber jumps from <10% CPU time to >95%
!!! 

2) Test two:
 I keep the number low <45 -> jabber cpu <10%.
 I go slowly down to one message pr 50 millisecond. After some 2-3 minuttes
jabberd crashes!!!
 
I though jabber was supposed to handle loads of clients (read thousands;
even with the limitiation of cygwin). And not certainly not eat all
resources at only some 40-50 clients.

If any one wants to test this, i can send them all components in the test
scenario.

Are these limitations wel-know or is it bugs?

regards,
lars.
