Qt Creator Performance Problems

Everyone's raved about how awesome Qt is and I would really love to use it. However, after downloading it and trying to build a little Hello World app, the performance of the Qt Creator slogged to the point of being unusable.

  1. The main problem is when I switch from "Edit" (code-view) to "Design" (form-view), it takes roughly 30-45 seconds for the form to draw every single time I do this. Here is a video of this happening.

  2. Hitting CTRL-R to run my application takes 30-45 seconds to display my application.

If anyone has had these issues, please post a suggestion! I would really love to use Qt.

UPDATE: After closing Qt Creator, I notice that Hg Workbench (Mercurial) takes between 1-2 minutes to open (where it's regularly instant).

I'd suggest you to run the application i.e., qtcreator from a command prompt. Since qDebug will be printing out crucial information about the actions going on, you might have a chance to understand what exactly is causing the slowdown.

Just in case., try the new QtCreator2.5.1 which runs well. Even if this doesn't work, probably there should be something wrong with the OS. Check for any programs that are running in the background which can be choking on the processor.
