Hi, Moving one my script to JMeter (3.3) I noticed a significant timing difference for some requests (between JMeter and measurements / other tools). For example, here is what I see in Fiddler for one request:

I see some difference in other requests too, but this one looks as a better example (my guess is that the difference becomes bigger for larger requests - and this one returns 7M). Everything inside a single data center, latency (ping) < 1 ms. Any thoughts? Thanks,Alex
