Update: Sorry, I made a mistake: in case use qjs.exe, my unittest skip run this code.

See the test, I don't know how it happened.

CPU:

  • AMD A6-3500 APU ( 3 core @ 135MHz * 6 )

System:

  • Windows 7 64 bit

GCC:

  • GCC 9.2.0 @ MSYS2 MinGw 64 bit

Test code:

for ( let i = 1; i < 10 ** 7; i ++ ) { i + 1 }

Case A:

  • _quickjs.cp38-win_amd64.pyd
  • Average time cost about 4700 ms

Case B:

  • qjs.exe 64 bit
    - Average time cost about 800 ms
  • Average time cost about 5000 ms

Can you post the compiler flags used to compile qjs.exe?

So, I tested them again. The real situation is contrary!!

Case A:

  • _quickjs.cp38-win_amd64.pyd
  • Average time cost about 4700 ms

Case B:

  • qjs.exe 64 bit Makefile
  • Average time cost about 5000 s
