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.)
