JMeter，带循环的请求率 controller

Question

I have this situation:

• LoopCount
  • BeanShell prepocessor (calcualte some parameters to pass to java request object)
  • Java Requests

With this setup the rate reached is 1 req/sec.
Is it possible, maintaining this structure, to increase the rate of requests?
Thanks everyone!

Answer 1

There are 2 constraints which limit the "rate":

1. JMeter must be able to send requests fast enough
2. Application must be able to respond fast enough

So I'd suggest taking the following steps:

1. First of all try switching from Beanshell PreProcessor to JSR223 PreProcessor with Groovy as the language because Beanshell interpreter might be the bottleneck .
2. Try increasing the number of threads in the Thread Group because if you have only 1 thread and cumulative elapsed time of the PreProcesor and Java Requests is 1 second you won't be able to run the requests faster
3. If you're limited with your machine resources - try running your test in distributed mode
4. If after applying the above suggestions you're still stuck at 1 request per second rate - most probably it's the system you're testing limitation
