I ran a microbenchmark on PR 8826: ./python -m perf timeit -s 'fmt=b"%s%s"; args=(b"1", b"x"(10241024))' 'fmt % args' -v -o patch.json $ python3 -m perf compare_to ref.json patch.json Mean +- std dev: [ref] 325 us +- 7 us -> [patch] 36.2 us +- 1.1 us: 8.98x faster (-89%) Ooops, yeah, it's obvious that there was a missed optimization. It's now way faster ;-)

I ran a microbenchmark on PR 8826:

./python -m perf timeit -s 'fmt=b"%s%s"; args=(b"1", b"x"*(1024*1024))' 'fmt % args' -v -o patch.json

$ python3 -m perf compare_to ref.json patch.json
Mean +- std dev: [ref] 325 us +- 7 us -> [patch] 36.2 us +- 1.1 us: 8.98x faster (-89%)

Ooops, yeah, it's obvious that there was a missed optimization. It's now way faster ;-)
