I made an schedule like that; 5 minutes time, starting vusers 1 concluding 5. Linear approach.

1. Some time test session ends at (5, 5) n mostly at (5, 0). (I didn't make any change, just repeat the schedule again n again).

2. For example I have 5 vuser running, stats shown for throughput is 5.2 MB. Now when these users become 50 its slightly increased to 5.6 MB. I think it should be much more as the number of vusers are more.
