500 concurrent users
Hi all friends,
1. I use OpenSTA version 14.4.4. and recorded 20 scripts and need to test with 500 concurrent users. And I want system only increase one user until enough 500 concurrent users in system. Pls show me how to set this?
2. And Someone pls explain to me about Interval between batches and Batch ram up time.
Total number of virtual users for this task group is 400
Interval between batches: 20
Number of virtual users per batch: 1
Batch ram up time(seconds): 15
I means: the first user run in 1st batch in 15 seconds then after 20 seconds the second user run in 2nd batch in 15 seconds? Do I understand right or wrong? Pls help me clearly?

You have it right. However, if you batch increment size is 1, then it would be much clearer to understand if you set;
total vus 400
interval between batches 35
num vus per batch 1
batch ramp 0
This would (in theory!) produce the same results as the setting you posted (400, 20, 1, 15)
