研究方向

先檢視 issue 中描述的三個基準測試領域,以及其中連結的現有 pydantic 基準測試。將這些選項與目前的 pyperformance 基準測試套件進行比較,接著釐清應納入哪些案例與基準測試程式。達成具代表性的基準測試範圍共識,並將選定的基準測試 upstream 後,即表示完成。

描述

Due to a current lack of representative macrobenchmarks, it is very difficult to decide on whether complex accelerators for some parts of typing are worth implementing in the future. Hence, I'm trying to upstream some benchmarks into pyperformance.

IMO, there are three main areas:

  1. Performance of static type checkers implemented in Python (e.g. mypy). (Fixed by #102)
  2. Performance of programs using types at runtime (e.g. pydantic, attrs, etc.).
  3. Runtime overhead of typed code vs fully untyped code.

For case 2, I plan to use one of pydantic's benchmarks here https://github.com/samuelcolvin/pydantic/tree/master/benchmarks, installed without compiled binaries.

Case 3 is very tricky because there are so many ways to use typing. I don't know how often people use certain features, whether they type-hint inside tight loops, etc. So I'm struggling to find a good benchmark. An idea: grabbing one of the existing pyperformance benchmarks, fully type-hinting it, then comparing the performance delta may work.

CC @JelleZijlstra, I would greatly appreciate hearing your opinion on this (especially for case 3). Maybe I can post this on typing-sig too if I need more help.

Afterword:
All 3 cases benefit from general CPython optimizations. But usually only 3. benefits greatly from typing module-only optimizations (with 1. maybe not improving much if at all, depending on implementation).
