I have found that my program runs much slower when using Wine compared to
running it directly on Windows. On Windows, it responds quickly, but when
running with Wine, there is a delay of three to four seconds. After analyzing
the program code, I discovered a loop within which semaphore operations are
performed. The time consumption for a single semaphore operation is 10-4
seconds when using Wine, whereas it only takes 10-6 seconds on Windows.

I wrote a demo program to test it and indeed confirmed this. Semaphore
operations are just one example; some other Windows APIs are also significantly
slower when compared to Windows. Is there any way to optimize this?
