I hope and guess that this problem has already been recognised by the GTK developers and they hopefully work on it. i just tried two GPE images on an iPAQ h5550 yesterday. One using GTK 2.6.x and one using GTK 2.8.x. Comparing the behaviour without any measurement 2.8 just feels slower. Like discussed before memory usage is another issue... I would like to have Cairo as a compile time option and not a fixed dependency. For small devices like the 770 or other PDAs you could then go without it (or slower devices). This would be a good solution, but this would lead to the situation that you can have incompatible builds of the same GTK version. I guess this is the main reason why the GTK developers only provide a very few compile time options. For example disabling deprecated bits at build time would be such an option too. It would save some space and make sure developers do not use deprecated features anymore.

Re: [maemo-developers] Re: testing pango with 770
Hi Eric, This is so interesting since GTK+ applications feels so much faster on all machines I've been using whereas QT once are somewhat slow.. Are you running them all in KDE? I'm running everything in Gnome and it's fast enough even on my 800MHZ machine at home. I have to admit that I also use KDE but I am not a fan of one or the other I just use it because I like its filemanager more than gnome's. For pure GTK apps it should not make any difference wether they run on KDE or Gnome except initial loading time which is not what I am talking about. All the stuff I talked about is from the user point of view, it is not my intention to flame arround nore I am a fan of QT or GTK apps which I would like to highlight. I am just a bit dissappointed by the performance of some GTK2 apps, thats all. These are just some impressions I had on my systems: * Konqueror has a faster UI than Nautilus * Opera has a faster UI than Firefox (whereas Mozilla GTK-1.2 builds where pretty snappy till they switched to GTK-2) * The Motif an Fox-Potrs of Eclipse are MUCH faster then Eclipse/GTK2 * Layouting works usually more smooth (=higher update frequency) wen resizing something with QT than GTK. * Even smaller UIs like that one from GFTP feel a bit slow if you resize the views. However that are just impressions, I did not make any time-tables to document behaviours nore do I say QT is better than GTK. I would be just happy if GTK would receive some intensiv profiling and tuning versions instead of new features to be on the line with other toolkits from the performance point of view. It could also be the case that GTK apps suffer a bit form the nvidia-drivers since I use nvidia cards on all of my 3 systems. Thanks for listening, sorry for bothering, lg Clemens ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Could you give names of the applications you've used for the comparison? E.g. was this Kword vs. Abiword etc (and not Kate vs. Abiword :))? I think it would then be pretty straightforward to get some hard numbers with xresponse. Note: In Maemo UI user cannot resize windows and applications themselves do that very rarely for dialogs, so this is fairly moot point for Maemo. - Eero ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

I absolutly agree - GTK-1.2 has been a nice and fast toolkit but since the jump to 2.0 GTK is just one of those too-bloated-to-be-tuneable pieces of software no one wants to touch since it could break something. And do not argue that big, feature richt toolkits are slow in general - Even large QT apps are snappy and very responsive whereas many large GTK-2 apps tend to be unuseable on slower systems (like my Dorun-800). 800mhz to render some buttons and layout texts?? Maybe I am just too old to understand whats going on :( A very favourite argument is that skinned toolkits are slow or X is slow, but how do other, much faster toolkits face with that.
