SocketException under heavy load

[roman_heinz]

Hi *.

I just startet evaluating jboss 2.4.1 on W2k.
First, I tried out jboss-tomcat with a simple war (no EJBs) and an ear with session and entity beans.

When I simulate about 10 or more concurrent users, tomcat starts throwing SocketExceptions after a while.
This happens with both applications, ear and war.
(and with the supplied tomcat-demo)

When I use Jetty, no SocketExceptions are thrown at the same load, but (without further configuration/tuning) jetty seems to be pretty slow.

Any ideas?

Slow compared to Tomcat - or something else ?

Slow compared to tomcat.
Note: I ran it "out-of-the-box", just added a
Datasource and did no real investigation.
One thing I noticed was, that there was never more
than one database connection out of the Pool?!?
