Re: [pypy-dev] Program slower on Pypy 7.3.3 (3.7.9) than CPython 3.9.
I put a small SSCCE for this at https://stromberg.dnsalias.org/svn/regex-fodder/trunk It's almost 10x slower, not quite as much as music-pipeline.

[pypy-dev] Program slower on Pypy 7.3.3 (3.7.9) than CPython 3.9.
And it's opensource, though many of the inputs are licensed. The code is at https://stromberg.dnsalias.org/~strombrg/music-pipeline/ ( https://stromberg.dnsalias.org/svn/music-pipeline/trunk/) It appears to be more than 10x slower. I haven't profiled it yet. I believe it's probably the "Blocklisting files..." part that's slow. That part is O(n*m), and seems to take forever. It's heavy on regular expressions. Are regular expressions expected to be slow on Pypy3? Thanks. -- Dan Stromberg ___ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
[pypy-dev] Release 7.3.4
I would like to release new versions of PyPy for python2.7 and python3.7. I think 3.7 has matured to the point that we can drop both the "beta" label and the python3.6 release. The python3.8 version is not yet ready for an "alpha" label. There are three issues (one about running "pypy -Wonce ..." and warnings inside a decorator, and two having to do with sqlite3) marked as blockers [0]. Are there more blockers? Anyone want to take a look at fixing them?
