Jmeter for loop http request - parallel

Question

I am using JMeter for image load testing. I have an array of the image name and looping over that array, I am getting all the image via HTTP request.

-> loop_over_image - for loop controller
   -> http_request sampler

for now, it will loop and fetch images via HTTP sampler one by one.

It is possible to make these request parallel.

I am looping over 300 images - means 300 HTTP request, it is taking more than 5 minutes, but in chrome, it is taking 30 seconds because chrome API requests are ASYNC - means kind of parallel.

Is there any way to make these 300 request parallel. I don't think it is possible, because the loop will go to each image one by one.

Answer 1

I am looking for the same solution. I am extracting from an HTTP response a list of urls and assigning them into a variable (as array). Parallel controller will not work in this case, since it does not accept an array as an input.

I think that there is not simple way to do it (possible using Java and JSR223Sampler). JMeter dev community should add this feature to JMeter.

I've opened an enhancement request https://bz.apache.org/bugzilla/show_bug.cgi?id=63526 Please vote up on it, so it will be implemented.

Try with parallel controller or sampler. Kindly check the below link:-

Hope this helps.
