Performance problems
I am having BIG performance problems just running a simple (Hello World)
type program under Suse Linux 7.1. My setup is ;
JAVA (SUN) 1.3.1
TOMCAT 4.0.1
SOAP 2.2
JavaMail 1.2
Xerces-J 1.4.3
JAF 1.0.1
And the JVM is set to -classic in jvm.cfg.
When I run the client (built with the same s/w as above) on either the same
Linux box or on a different NT Workstation V4 box, the response time from
hitting enter to getting the response is around 3 seconds.
This application is v.simple (copied from a JavaWorld article at
http://www.javaworld.com/javaworld/jw-04-2001/jw-0427-soap.html).
To get it all working I changed catalina.sh in the tomcat/bin directory to
include the above components in the classpath as follows ;
CP=$CP:"/home/steve/soap-2_2/lib/soap.jar"
CP=$CP:"/home/steve/javamail-1.2/mail.jar"
CP=$CP:"/home/steve/jakarta-tomcat-4.0.1/common/lib/servlet.jar"
CP=$CP:"/home/steve/jakarta-tomcat-4.0.1/server/lib"
CP=$CP:"/usr/java/jdk1.3.1_01/lib"
CP="/home/steve/xerces-1_4_3/xerces.jar":$CP
CP=$CP:"/home/steve/jaf-1.0.1/activation.jar"
CP=$CP:"/home/steve/soap-2_2/samples"
The above lines were added after the CP env.var is set.
The Java Profiler shows no real CPU usage.
The CPU monitor shows the CPU pushing 100% for a brief period.
The hard disk light flickers briefly (logging ?)
I guess my setup is wrong somewhere but I have no idea where.
Is anyone else running this config ?
Any help will be very gratefully taken.
Thanks in advance.

We have a rigidly enforced E-mail Standards Policy. Any E-mail or E-mail
attachment that is in contravention of this policy would be outside the
scope of authority of our employees.

Of course. I didn't know that you count everything from the beginning...

I think that the main bottleneck is in Tomcat HTTP processing. Did you try
other HTTP server?

We cannot compare those 3 seconds with the 500 roundtrips per second. In the first case, the 3 seconds also include the startup time for the JVM, the initialization, etc..., which is not true in the second case.
My own tests, running in a WinNT environment, gave something like:
-about 3 seconds when running a client which would perform a single request;
-about 4 or 5 roundtrips per second when my client performs a loop of simple requests;
-about 15 roundtrips per second after I added a "setTcpNoDelay(true)" in one of the SOAP classes(HTTPUtils.java)

Since I got some follow-up questions, I just want to say it more precisely:
This number does not mean a throughput. It means a number of individual
sequential roundtrips between one client and one server. I.e. one roundtrip
is about 2 ms.

Re: Performance problems
Posted by Radovan Janecek <ja...@systinet.com>.

This number does not mean a throughput. It means a number of individual
sequential roundtrips between one client and one server. I.e. one roundtrip
is about 2 ms.

Eh - no - most setups deal with some 10's of messages a second at the very
least; esp. when the RTT is short. With longer round trip times and real
long distatn conenctions you'd front it with apache anyway - so that
offloading of the stack would again give you 10-100's of connectioons even
on the most modest hardware (say a 450Mhz Apple iBook / 256Mb / MacOS X).

I'm a little confused. 3 seconds over HTTP is a
performance problem? Sounds about average to me,
especially with XML parsing involved at both
ends...please correct me if this doesn't make
sense.
Anybody got a good reference URL to a digest of
the SOAP performance debate?
