Help needed: Fastest compiler for aom-psy101

[Uranite]

I’m seeking advice on the best compiler to use for building aom-psy101, specifically to maximize performance.

So far, I’ve tried the following:

• MSVC
• GCC and Clang via MSYS2
• Clang and Clang-CL via Ninja
• Clang-CL using the -T ClangCL flag

From my initial testing, I found that MSVC and GCC (MSYS2) are slower than any of the Clang variants. However, the performance of Clang (MSYS2), Clang and Clang-CL (Ninja), and Clang-CL (-T ClangCL) appears to be roughly equal. That said, my testing has been brief, and more thorough comparisons are needed to determine which is truly the fastest.
