In the package containing the simplified tool for generating and executing load/performance tests for QV you can find a link to JMeter version 2.4 in the prerequisites document. However, it has been verified that the tool runs fine with JMeter v. 2.5 as well (for both QV10 and QV11). Download the package/tool from http://community.qlik.com/docs/DOC-2705
The package/tool has been released to simplify and automate many of the manual steps described in the tutorial. For performing a load/performance test with JMeter our advice is to use the tool.
