Jmeter threads slow to start

Question

Excuse my basic jMeter knowledge.

My script has 5 thread groups, one with two threads, three with 1 thread and then the final group with 30 threads. When the final group runs it runs first for 1 thread then when that thread has completed it will run the 30 threads concurrently including that thread 1.

Any clues on how I can get that thread group to kick off with all 30 threads when it starts? Instead of initially with just 1 thread.

Thread group config

Test plan config

Inside the thread group in question there is a double nesting of loop controllers, which seem to work correctly.

Hope you can help thanks.

Answer 1

If i understand your question correctly then in my opinion, there is an option in the Test Plan which says Run Thread Groups consecutively-- Uncheck the same and then execute your run, it should work..!!

Answer 2

You most probably checked by error "Run thread Groups consecutively" option in Test Plan:
