runghc is slow

Computer information
OS: Windows 10 22H2
Architecture: x64

Hello, I have installed Haskell in Windows throw the Powershell command provided by the official website. I have installed it in a existing msys2 installation. The issue I have is that when executing 'runghc' command in msys2 prompt, it takes about 8 seconds. I do not know if it is normal in Windows, but in Linux it takes less than 1 second with the same source code (a hello world print). I also have to mention that when verifying the version of runghc have a good time response (less than a second).

I made a trace command and I noticed that the part that takes the longer is just before the print of the hello world in the line "--- Process 10944 loaded C:\ghcup\ghc\9.4.8\mingw\bin\libwinpthread-1.dll at 00007ffc72f20000".
I would appreciate help or information about this "problem". Thank you very much.

Here is complete output of the strace command:

GHC brings it's own installation of msys2. You need to report it to the GHC project.
