Add simple memory allocation benchmark by tiran · Pull Request #132 · python/pyperformance

Does it belong to pyperformance which is supposed to be a set of "macro benchmarks"?

I would say yes: we have things that are quite small in what they do anyway. C'mon, we even have unpacking tests:

for _ in range_it:
# 400 unpackings
a, b, c, d, e, f, g, h, i, j = to_unpack
a, b, c, d, e, f, g, h, i, j = to_unpack
a, b, c, d, e, f, g, h, i, j = to_unpack
a, b, c, d, e, f, g, h, i, j = to_unpack
a, b, c, d, e, f, g, h, i, j = to_unpack
a, b, c, d, e, f, g, h, i, j = to_unpack
a, b, c, d, e, f, g, h, i, j = to_unpack
a, b, c, d, e, f, g, h, i, j = to_unpack
a, b, c, d, e, f, g, h, i, j = to_unpack
