Hello all,
I tried:
- isolating code in a java class and running it on both machines, about same
performance
So, the machine itself is OK.
- running tomcat 4.1.29, bit faster but still ~15 sec.
- changing network connection to full duplex, 2*faster but stil ~6 sec
(should be
enableLookups=true .
..
/Connector
Maybe the reverse lookup is failing?
Just a guess...

Hi Johan
It's very suspicious that websphere runs so fast and tomcat doesn't. I
think
there still might be a network issue.
Can you modify your server.xml as follows changing the
enableLookups=false
instead of enableLookups=true
Connector port=80 minProcessors=5 maxProcessors=75
.
Cheers,
Johan

Any chance there is something else running on the machine that's killing
the
performance.
You should post the specs of the machine if you expect a reasonable guess
as

This kind of performance degration can
also have some of the following causes if
the load of the system doesn't indicate
a problem:
- long or failing DNS Lookups

I doubt it is jasper, but it is possible it could be. I wouldn't rule it out. You
