I just decided to redo some of my tests with RC1 so I could cast a vote, and some weird things happened. Possibly good, but weird.
First, I had to change my PYTHONPATH in one spot to say 2.7 instead of 3.9 as it was before. Is that correct? But second, performance on the test I picked -- 'hey' sending HTTP requests through 1 router to nginx with 10 parallel senders -- has changed a lot! After seeing the first result I ran it four more times. This is exactly the same test I used before -- I have saved the test scripts and config files, etc, in separate directories so I don't have to think to re-run the tests. *Executive overview:* Requests per second have risen by 70%. The 99% mark is much faster. The really horrific slowest-measurement did happen once, but it did not happen on the other four tests. I thought nothing significant should have changed. What Just Happened? Test: scenario 2 (1 router), 10 senders, TCP adapter (This is 'hey' sending http requests through one router (TCP) to nginx.)
