400MHz? Slower than a N900? I think your problem might be processor speed paired with the enormous structure that is modern toolkits.
....Is your computer always that slow? Graphics card? Only Qt applications? Only QtCreator?
@TheAccountant: When you say that "Qt by Nokia is really slow on my box", and then talk about desktop performance, are you speaking of issues with the Nokia SDK/Qt Creator, or general performance issues of Qt-based software on the Linux distros you've tried (with KDE Plasma Desktop?)? I used to use a P IV system for Maemo development before I got my new machine, and it is going to be slow, just because it's old. If the problem is general desktop performance, then from what you said, the first thing I'd check is that any eyecandy is turned off. If your computer is that old, and the video card isn't very good (for that era, even), then leaving desktop effects on is going to have that effect. What was your Arch setup like? Arch is pretty darn slim by default, so I would be inclined to think that if you had the same issues there, it might be something else, rather than the sole fault of a specific technology.
Hi TheAccountant, I'm currently trying out the Nokia QT SDK beta (ie, QT Creator with QT 4.6 and MADDE integrated) on my laptop. The Laptop is a Vaio TX running Ubuntu Lucid. The CPU is a U1400 @ 1.2GHz. Runs fine here. If you can give a concrete example of exactly which menu items are slowfor you perhaps others can try to reproduce. Cheers, - Micha.
