Bug ID: 48616
           Summary: Using wchedtool slows down program
           Product: Wine-staging
           Version: 5.1
          Hardware: x86-64

Very slow performance when running a program with schedtool only on one CPU.

This Problem appeart between wine 3.1 and wine 3.2

Problem : When running a program which requires to be run on only one CPU (e.g.
heroes of might and magic 3) - if running on Dualcore CPU's  the program
crashes sometimes in mp3dec - the entire program runs like in slow motion, even
the mouse pointer moves very slow.

The Program itself runs, but the speed of executed program is too slow for
playing.

Wine Version 3.1 is the last working one correctly with schedtool.

The command is : env WINEPREFIX="/home/hero/.wine" schedtool -a 0x2  -e wine
C:\\windows\\command\\start.exe /Unix
/home/hero/.wine/dosdevices/c:/users/Public/Desktop/Heroes\ of\ Might\ and\
Magic\ 3\ Complete.lnk

It doesn't matter if the program is running on cpu2 or cpu1.
