I just tried running a program that I've been developing with Qt outside of Qt. I double clicked on the program in /release, resolve all the missing DLLs, and find that my app has awful slow performance compared to when it is launched from within Qt Creator. What might be the reason for this?!
A:
Well, I have never encountered this. Is there any files you are loading in your application which is big enough to make the application load slow? Like reading a big flat file and get the contents out of it. If so, just make sure that the file's contents hasn't changed while you were running through Qt Creator and when you run it outside. It's my guess though. For me, the performances doesn't have much differences in either cases.
