The most obvious thing that jumps out here other than raw MHz is that you
are running C2.1-dev on the Sun and C2.0.3 on the PC, so you aren't really
comparing apples to apples.  Maybe that isn't a factor, but I would
certainly want to check it out before anything else.  Especially with that
"-dev" dangling on the end.  Ditto with JDK versions - you could have a
quirky JDK1.4 release or something.  And ditto again with Tomcat versions;
you can run the full Tomcat 4.0.4 (not LE) under JDK1.4, works just fine.
You should also check that you have a level playing field in every other
way, e.g., make sure your Sun isn't running something else (like a database
server), make sure the Sun is on the same piece of network (instead of
across a slow T1 to another building), etc.

It appears you have an older Sun workstation, while your PC's are very,
very new technology.  If you are planning to deploy to a newer Sun server,
like a Sun Fire 280R with 900 MHz UltraSparc III Cu and 1 GB of memory, I
imagine you'll get better results.

FWIW, we deploy on one of Sun's cheapest servers, which has a single 500
MHz UltraSparc IIe and 1GB of memory.  The server is dedicated only for our
application.  On the other hand, we develop on older PC's with 500 MHz and
1 HGz PIII's and 256 MB of memory.  Performance on the servers is quite a
bit better than on our PC's :)

Hi all

We're developing a cocoon-application (so far only xslt pipelines,
no apps) on a SunOS server.
Everything works out well, but we're experiencing heavy
performance problems. To make sure our application could
be running fast, we tested it on a PC, which resulted in more
than ten times faster response times. Which would be perfect,
only SUN is our target platform.

Are there any known issues about different jdk-versions?
tomcat-versions? cocoon-versions? SunOS?, pitfalls? any
tips to boost performance OR is our Sun Machine simply to slow?
(see technical spec details below)

Thanks in advance.
Thomas Brusa
