Giving more memory to Web Performance 3.4 while load testing

First do not trust their documentation! The launch anywhere (lax) file change doesn’t make it.

Do it by your own, with such a command:

"C:\Program Files\Web Performance Suite 3.4\webperformance.exe" -vm "C:\Program Files\Web Performance Suite 3.4\jre\bin\javaw.exe" -vmargs -Xmx512M -Xms512M -jar "C:\Program Files\Web Performance Suite 3.4\startup.jar" -os win32 -ws win32 -arch x86

Thanks Robert for the support.

I've edited the lax file and changed the memory settings "-Xmx512M -Xms512M" myself and haven't found any problems.  If this isn't working for you, please let us know!  You can file a support issue at support.webperformance.com

Obviously having to edit a file isn't the best solution, but unfortunately the JVM can't dynamically allocate more memory to itself past the top limit, and because of the real-time nature of simulating web users, we can't have the VM allocating memory in the middle of a test.
