If you can read Python and shell script, then checking I haven't made any obvious coding errors in my changes would help. But that might require becoming familiar with the codebase - which may take some effort.

The diffs are here, or you can use git diff:
https://github.com/teor2345/chutney/compare/feature14175-chutney-performance-v2
https://github.com/teor2345/tor/compare/feature14175-chutney-performance-v2

Also, I was only using Python 2, so I might have accidentally introduced some incompatibilities with Python 3.

Since it's the localhost, CPU-limited, massively-parallel bandwidth, there's no "correct" value.
I'm not even sure what sane values are, but we'll get an idea once people start competing for the biggest numbers.

Does it run?
When you make performance improvements, does the bandwidth increase?
(Or, far more easily: when you deliberately slow down the code, does the bandwidth tank?)
