Hi, I have been using JMeter for about 2 months now and I have a couple of general comments on how it could be improved. Firstly, I appreciate all that the JMeter team has done, so please consider the below constructive suggestions:
1: I know we all hear this, improve the documentation. There is a lot of scope for misinterpretation. I must have gone through the distributive portion of the documentation a dozen times and I still can't get it to work remotely. 2: Why is it using so much memory? I have a threadgroup that simulates 20 threads going through 5 pages. After about 5 minutes all my memory is maxed out and the program stops and all I have is a java.lang,outofmemory exception on the dos window. I have 256 meg of ram, is this not enough? 3: While the program is running I see a lot of exceptions being thrown in the dos window. Most of them have to do with RegExp classes etc. While the program seems to run, should I be worried? Maybe it would be better to hide this from the user. 4: How do I simulate a lot of users? I tried using one test client but I can't go higher than 30 thread or my machine runs out of memory? I tried the distributive framework and I can't get that to work. If I could I probably could not simulate more than 30 users. How about a set-up where you could put clients on a number of machines that are controlled from one central location, so that when you run a test at your desktop, simultaneously they also run from these clients? 5: I know it has been mentioned before but the GUI could be improved. The ability to move test elements around etc. Also, screen redraw seems to be problematic. If I switch the look and feel to windows, and then click through my test most stay with the default look and feel until I click them. For the record my desktop is a PIII800, win 2000, 256 meg ram and jdk1.3. Just some thoughts for your consideration. Alex
