[Solved]Qt 5.3 application ran in terminal EXTREMELY slow.



  • So I have an application that when I run it inside of QtCreator it works just fine, but when I just try to open the file explorer, terminal, or QtCreator option "Run in Terminal" on, it runs PAINFULLY SLOW. I can't figure out why running in a terminal slows it down so much. Btw, this is a Qt Quick 2 application on a Windows XP system. Has anyone ran into this problem?



  • @Buttink If anyone comes across this problem. Apparently, the QLoggingCategory or the stderr/windows debugger are SUPER slow on windows. To fix this I used qInstallMessageHandler and wrote my own handler to not send to the terminal for windows. Now, my application runs just fine.
