I wish did fix the issue. I've used VIM for 10+ years, but never really into VIM scripting (always subjectively beliving that this was one area where VIM was weaker than Emacs). , The best advice I can give is that you read:
With these it helps Read about SLA I recommend you to determine your requirements of web-site performance. But by default you can use "standard" response time limit about 10sec. Next, find user activity profile during day, week, month. Then you could choose base values of load for each profile. Find most frequent and most "heavy" user actions. Create test scenario with this actions (remember about percent ratio of actions, don't use all actions with one frequency). Limit load by throughput timer (set needed value of hits per minute). Number of threads in thread group select experimentally (for http load not needed many of them). Add plugins for jmeter from google-code. Use graphs "number of threads in second", "response time" and standard listener "summary report". Don't use standard graphs with high load, it's too slow. You can also save data to file from each listener (I strongly recommend this, and select csv format). Graphs show average points, so if you want precision pictures then build graphs manually in excel or calc. Grab performance metrics from server (CPU, memory, i/o, DB, net interface). Set ramp up period about 20-60 minutes and test about 1-2 hours. If all right, then test with 200% load profile or more to find the best performance. Also set test about 1-2 days. So you'll see server stability.
