We have a very basic web script that has 2 requests.
When we run a test using JMeter, we're able to test to around 200TPS with 400 threads. However when we try to run the same test in HP (400 VU from the same host) the LG becomes a bottleneck at 80TPS due to a CPU constraint.
We've reduced also logging in HP and tried with different think times and increased iteration pacing, however this hasnt changed the result.
Does anyone have any ideas about this? Is it expected that HP VUs have a larger resource footprint than JMeter?
