David Klassen commented on AXIS2C-717:
--------------------------------------
As you will notice the platform in question for this bug is Windows, not Linux.
Yes I know that it sounds odd to use Apache on Windows, however it seems to
provide better performance than IIS for axis2c. Essentially the attempt was to
find a platform we could offer for those who need to use Windows (Because of
preference etc. etc.), and at the same time also offer the dist. on the
platform I prefer (NIX). On Windows it seems we cannot provide process
pre-forking, since it is not recommended:
http://httpd.apache.org/docs/2.0/platform/windows.html#cust
http://www.devside.net/articles/apache-performance-tuning
So perhaps the issue for axis2c is the same as that of PHP:
http://www.php.net/manual/en/install.windows.apache2.php
I guess I should have researched this quite a while ago, unfortunately I
assumed apache would work well since it now also provides all the normal
Windows platform related material (Install packages service invocation etc.).

> Key: AXIS2C-717
> URL: https://issues.apache.org/jira/browse/AXIS2C-717
> Project: Axis2-C
> Issue Type: Bug
> Components: guththila, platforms/windows
> Affects Versions: 1.1.0
> Environment: Windows XP Professional SP2
> Apache 2.2.4 server with Axis2c 1.1.0 module
> - Remote stress test client script hosted by Fedora Core 7
> Reporter: David Klassen
> Assignee: Dinesh Premalal
> Fix For: 1.2.0

>
> I wanted to stress test axis2c deployed on apache, to see if using this SOAP
> implementation would be reliable. Simulating 25 concurrent users (with a
> shell script) making one request per second by using the 'echo' sample
> program (recompiled to target the server from a remote machine[Linux]). With
> Gnuthilla compiled-in axutil.dll suffered an Unhandled Exception
> (repeatably). While Gnuthilla did suffer less memory consumption, when the
> httpd.exe memory consumption reached around 77 MB the exception was
> triggered.
> Here is what my VS 2005 debug session provided me:

> Seeing that this is a thread, I cannot be sure if the error was triggered by
> apache or something else. I guess this might be something apache specific? It
> is interesting to note however that this happens consistently with gnuthilla,
> whereas without it a crash does not always occur (ie. Only some of the time).
> Without gnuthilla the httpd.exe process sometimes reaches 200 MB or more
> without crashing. Still trying to figure out what causes the net memory
> consumption, since even when the 25 clients are stopped the httpd.exe memory
> size does not decrease.
