QT Creator running debug too slow

[Infinity]

Is somebody familiar with this situation

Actually I have the same problem. Debugging on Windows using MinGW is slower compared to debugging with GCC on Linux. On Linux there is no noticable performance loss whereas on Windows especially launching the application takes slightly but noticeable more time (both operating systems/compiler are running on the same machine).

and could provide some tips on how to speed up running of gdb in Qt Creator

Unfortunately I haven't solved the problem. The only tip I can provide is the usage of Linux/GCC instead of Windows/MinGW.
