Runtime is very long

[vsolskyyy]

Hello, when running my program with mypy, runtime can be very long. My team has to run the program a lot, so I was wondering if anyone else was running into this issue, and if anybody has any tips. Thank you

Long analysis time can be caused by many factors. Some of the more common causes are: a large number of source files in the project, files with many lines, a large number of overloads, large union types, and deeply-nested expressions.

Also, different type checkers have different optimizations. Pyright is often faster (sometimes significantly so) than mypy, but this is dependent on the code being analyzed.
