Hi! Few days ago I also realized that invoking java script takes too long. To fix it you can try those things: 1. instead of using rhino library in version 1.6.x try to use the newest version: 1.7.2 it can give fiew percentage, this speed up my tests a little. 2. change org.apache.jmeter.functions.JavaScript to use default javascript engine available with jdk6 (use ScriptEngineManager and ScriptEngine class) it should boost your tests twice or more, but I'm not sure if those engines are 100% compatible, it works correct for my.
I spent several days to optimize jmeter and I must say that functionality of this tool is great but performance is dramatic low. It almost impossible to make stress test, because after collected 300 000 - 500 000 samples, jmeter performance drops rapidly (even if test use only one listener: aggregate report). I checked that before optimization after 1 hour stress test jmeter showed throughput 450 req/s of my server, after optimization throughput is about 5000!
