[pypy-issue] [issue1653] performance regressions in benchmarks

[Armin Rigo]

Armin Rigo <armin.rigo at gmail.com> added the comment:

If I remember correctly, the recent noise was introduced by the jit-counter
branch, "expectedly" because it is now more prone to random collisions that can
have particularly an effect on some kinds of small examples (e.g. by getting
first one version or another compiled as a loop, then the rest attached as a
less-optimized bridge).  I think that the level of random fluctuations is still
ok overall.

I haven't investigated the jump of Go in the beginning of July.
