In the same folder:

    time uvx mypy .    

Result:

    uvx mypy .  0.46s user 0.09s system 74% cpu 0.740 total

So ty is about 7x faster - but remember ty is still in development and may not catch the same errors / report false errors, so it's not a fair comparison yet.

Note that `uvx mypy` may give you inaccurate timings on macOS. The antivirus in macOS goes a little crazy the first time it executes a mypyc compiled program.
