For a cross reference... the environment I am running:
Apache SOAP 2.2 (+ a few minor custom alterations)
IBM Java 2 runtime 1.3
Windows 2000 Advanced Server
750Mhz, 128 MB
Tomcat 3.2.3 and/or WebSphere 4.0
One thing I did notice is that under WebSphere, the slow down is not as
bad, but there still is a slowdown. The slow down seems to occur using the
Sun runtime also.

The guy in charge of the Linux machine it's running on says he'll save the
memory and CPU usage next time we experience the problem, but for now, I
don't have that data. Also, so we can start keeping track of information
regarding this problem, here are the system specs we're running SOAP on:
-Apache SOAP 2.2
-Java 2 Classic Runtime Environment, Standard Edition (build 1.3.0)
Classic VM (build 1.3.0, J2RE 1.3.0, IBM build cx130-20010626 (JIT
enabled: jitc))
-RedHat Linux 7.1, kernel 2.4.3
-Compaq 1850R, 256Meg memory
-Tomcat 3.2.3

that is very interesting - was there any difference in memory or cpu usage
between old and newly
retsrted process? you may also try different JDK versions and different
OS...
