The code is fine, but it looks more like a microbenchmark. Have you compared 3.10 and 3.11 yet with this?

@ericsnowcurrently Do you think this makes a reasonable addition? I'm not sure where we stand on adding more microbenchmarks.

@kumaraditya303 The new files are missing trailing newlines.

One minor suggestion.

@kumaraditya303 We discussed adding microbenchmarks and the conclusion is that it's okay. So can you address the minor nits? Also, I am concerned about the greenlet-related failure in the 3.11-dev test. I am curious though -- how old is the 3.11-dev version on Ubuntu? Maybe it's an older alpha?

[kumaraditya303]

3.11 is failing because of compilation error when compiling greenlet. See the tracking issue python/cpython#92898, it is fixed in main branch and 3.11 but no release has that fix yet.

One thing microbenchmarks are very good at is finding regressions as it is focused on one thing only.

Thanks for the benchmark, and thanks for the link to the issue with greenlet!

@gvanrossum Benchmark results comparing 3.10 release and 3.12 main branch:

Benchmark	3.10	3.12
generators	299 ms	206 ms: 1.46x faster

Nice!
