Hello,
I have a quick question and I was looking for any insights or ideas to try. I am running Tomcat 3.3.1 with the JRE 1.3.1_03 server vm, and Xalan-J 2.4D1.
I wrote a small test program that performs a couple of transforms on some data that I have that happens to be a decent size. This transforms it in about 40 seconds each for the first pass, and usually 16 and 26 seconds each for the subsequent iterations.
When I am run the same two transforms from within a servlet running under Tomcat, it takes an unbelievably long time. We are talking on the order of 6-8 min. for the first transform, and 2-3 min for the second one.
For further clarification, the transformers are always derived from a Templates object. The system is a P3-800 with 256 MB of memory. When I run my test program, it sucks nerely 100% CPU for the whole time, and chews a healthy amount of memory. When I run from tomcat, it spikes the CPU to varying levels but never chews it consistently, while at the same time consuming apparently a bit less memory (or quickly gc'ing the memory).
In both cases, the Java heap is set to minimum 128 and maximum 512.
I would expect the time under the servlet to be a bit slower, primarily because there are other things that I am doing there that I am not doing in my test program, but these numbers are downright painful.
Any experiences with similar situations, ideas, thoughts, or pointers would be greatly appreciated!
Thanks in advance,
Mario-
