(original) (raw)

I was recently in need of some faster caching and thought this would be a good opportunity to familiarize myself with the Python/C api so I wrote a C extension for the lru\_cache in functools. The source is at https://github.com/pbrady/fastcache.git and I've posted it as a package on PyPI (fastcache). There are some simple benchmarks on the github page showing about 9x speedup. I would like to submit this for incorporation into the standard library. Is there any interest in this? I suspect it probably requires some changes/cleanup especially since I haven't addressed thread-safety at all.

Thanks,

Peter.

P.S. This was the motivation for the faster caching https://github.com/sympy/sympy/pull/7464.
