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 :) -Christopher 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.
