I am using Sun's JDK 1.2.2. I am not sure what JVM Sun's Java Web Server 2
uses, though. I don't know anything about the product.
> What database are you using? How where you using in JWS vs JServ?
We are connecting to an Oracle 7 DB. Each machine accesses the same database
so the database is consistent across setups. In other words, the Windows/Sun
Java server attaches to the same database as the Apache/Jserv attaches

The Apache/Jserv is on a dual Pentium 650. The Windows machine is a single
Pentium at a lower clock rate. However, since the Java itself is not that
CPU intensive (most of the work is done on the DB side), the CPUs do not
make a difference. If they did, I would expect the Windows machine to be
slower then the Apache/Jserv machine.

I will look into that. It sounds like a good idea. However, if I DO find out
that Sun's Java Webserver is faster, what do I do then? It seems that the
problem is in the JVM. Maybe switching in different JVMs?

That is what I would think, too.
