KDE 4: Understanding the Buzz (KDE.News)KDE 4: Understanding the Buzz (KDE.News)Posted Aug 12, 2005 6:29 UTC (Fri) by eru (subscriber, #2753)Parent article: KDE 4: Understanding the Buzz (KDE.News) From the linked article: Qt4 will bring a wealth of new benefits to KDE. The library is lighter on memory ... I'm wondering how much effect that will have on our bloat problem on KDE systems. Too bad he did not say. On the other hand, additions to KDE4 are likely to make it more memory-hungry anyway.

KDE 4: Understanding the Buzz (KDE.News) Posted Aug 12, 2005 9:04 UTC (Fri) by henning (subscriber, #13406) [Link] As she mentioned in the article, applications need to link only against the needed parts of the qt4 library. This should reduce the memory needed from running application.The upcomming kde-3.5 will additionally use (with gcc-4) the "-fvisibility" flag, that will hopefully further reduce the library size and load times. If you are concerned about the "bloat problem of kde", you could join the kde-quality or kde-devel mailing list on kde.org.
KDE 4: Understanding the Buzz (KDE.News) Posted Aug 12, 2005 10:00 UTC (Fri) by Duncan (guest, #6647) [Link] Yes... it /is/ a /she/. I just spent quite a bit of time looking over theentire site, including the blog and photo gallery (and having read the blog after checking the gallery, was surprised to find the gal I /thought/ was probably the girl friend or wife, was the photographer/author! so it wasn't just the OP making assumptions... <g>) I decided I quite like her photography style. The landscape and nature ones are nice, but the ones with people in them are what impressed me (nature ones are so commonly seen on calendars and the like). The people and environments seem almost "immersive" -- the textures of the jackets, the smell of the sea air... not so "artificially posed" or simply "uninteresting", just a bunch of people, as many people shots I've seen. She and her partner must be very interesting people. But... back to KDE. I run Gentoo, and got a chance to run the KDE 3.4.0 betas, compiled with gcc 4.0.0, before they decided they had more work to do on KDE's use of -fvisibility (buggy as implemented) and to remove it for 3.4 and put it in 3.5 or 4.0. No doubt part of the reason it made such a huge difference here was that I use on-load binding, in preference to lazy-binding, by default (for a number of reasons), but that -fvisibility stuff made a *HUGE* difference to my load times. It was almost as if initial uncached launch had already been pre-cached, and relaunch of apps already in cache was so fast it actually took a bit of getting used to! (When apps take a couple seconds to launch, one gets used to deciding to launch the app, and /then/ think about what they are going to do in it while it's loading. When launch is instantaneous, one fines it has appeared before one is actually quite ready to use it! <g>) Actually, I'm glad, if it had to be removed to be reworked for later, I didn't get to use it all that long, or it would have been /very/ hard to give up! I'd read about the -fvisibility feature, but this was one of those times when the reality actually surprised me, it was that much faster. So... yes, I'm /really/ looking forward to getting that feature fully enabled, once again! Duncan
KDE 4: Understanding the Buzz (KDE.News) Posted Aug 12, 2005 14:37 UTC (Fri) by henning (subscriber, #13406) [Link] AFAIK the upcoming qt-3 maintance release will include the needed patchesto enable the -fvisiblity support in kde. KDE >= 3.4.0 will then autodetect the support, and should enable it. Some time ago i tried to use a qt patch from kde-bugzilla with gentoo to enable this stuff, but with no luck. Thanks for your comments! I think in the next days i must try it again.. ;-)
KDE 4: Understanding the Buzz (KDE.News) Posted Aug 18, 2005 13:48 UTC (Thu) by pointwood (subscriber, #2814) [Link] Wouldn't that be quite hard to calculate?
AFAIK, KDE has been working on this for a long time and it hasn't become more memory hungry for a long time. I think KDE4 will be similar and wont require more memory than previous releases, it might even require less.
