JMeter startup VERY slow with large user classpath

[Kai Weingärtner <ka...@widas.de>]

Hello,

I am trying to load test a client app that connects to a weblogic server. 
The client app is a simple java app I planned to call from a java request 
sampler.

However, the client app needs several large jars which I added to the 
user_classpath. All in all I need about 43 megs of jars. But when I try to 
start jmeter with this user_classpath, it's not coming up anymore (in a long 
time).

My guess is, that jmeter is scanning the jars for implementors of 
JavaSamplerClient and this is taking very long. Is there a way to prevent 
jmeter from doing so?

I also tried non-gui mode with similar results.

Any advice on how to get this client app running in jmeter is welcome.

Kai

I don't think user_classpath is used by JMeter ...

There are two search paths that can be defined in jmeter.properties:

search_paths - this is used for JMeter jars; corresponds to lib/ext

user.classpath - this is used for utility jars, corresponds to lib

You have not said where you put the class with the JavaSamplerClient
implementation. This needs to be in lib/ext or equivalent classpath.

Everything else should be in lib or equivalent classpath.

I suggest you start by putting the jars in the lib/ext and lib
directories, and then try removing the jars and using the classpaths
instead.
