KDE It slipped by us, but the KDE team has released another minor bugfix release of KDE 4.2, version 4.2.3, a few days ago. Being a bugfix release, there are few user-visible changes, but still, there are a few things that stand out. "Online IMAP filtering in KMail has been fixed, KMail's system tray icon now reacts to changes to folder properties and updates the number of emails shown there automatically, and bugfixes, performance improvements and optimization in KHTML - painting and interoperability with web standards has been further improved."

I have a card that runs Compiz just fine and xcompmgr/kompmgr blazingly fast, but KDE4 is PAINFULLY slow. Every time I try it, it's still slow. I don't need to upgrade my hardware, they need to fix whatever crap they are doing that slows everything down. Heck, even without compositing enabled on KDE4, things are still slow, even apps that weren't laggy while running KDE3. I don't even know how they manage that.

And Qt4 is much slower than Qt3. With Qt3, I can smoothly resize windows both with and without compositing enabled. With Qt4, even without compositing, resizing windows is glacially slow and you can see the widgets struggle to re-lay themselves out. It's pathetic, really.

If you have a nvidia card, that is probably the cause of it. Nvidia graphics drivers for Linux have been very broken for over two years, and it was fixed only recently. If you have a nvidia card, then unless you have updated the nvidia drivers for Linux in the last couple of months, that is almost certainly it.

KDE4 is very fast ... PROVIDED that you have properly working hardware-accelerated graphics.
