Well I would bash KDE 4 but its flaws should be obvious enough to anyone that tires to run it on slower hardware (anything without opengl support or anything with a slow CPU or lack of ram)
KDE 3.x was good and I like Trinity desktop alot.... e17 and accociated libraries probably blow it away in the performance aspect and I hope that KDE 5 looks toward that direction and leaves all this nonsense behind.
This is all mere unsupported allegation. I run KDE4 on a recent but low-end, under-powered, low-RAM netbook, and it runs just fine. I have encountered no hardware that used to run KDE3 well that cannot now run KDE4 just as well.
Indeed there may well be old hardware out there with no GPU, a slow CPU and a lack of RAM ... but such hardware will not run ANY recent full-featured OS well. If you have such hardware you have no hope of running KDE4, GNOME, Windows 7, Mac OSX Lion or whatever on it, something like Puppy Linux is probably your only choice.
My question for you is this: why is an observation that there happen to be some older machines still out there which will not run KDE4, GNOME, XFCE, Windows 7 or Mac OSX well in any way a valid criticism of KDE4 in particular?
Hmmmm?
KDE 4.6 runs exceptionally well on an Asus eeePC 1005HA (1.6 GHz Atom CPU, 1 GB of RAM, 160 GB SATA HD, Intel onboard graphics).
KDE 4.something (it's been awhile) run fairly well on an Asus eeePC 701 (600 MHz Celeron CPU overclocked to 900 MHz, 512 MB RAM, 4 GB SSD with 2 GB SDCard, Intel onboard graphics), although an update to the Intel driver screwed things up (constant screen flicker) and I haven't touched it since.
KDE 4.6 runs exceptionally well on a generic desktop (2.8 GHz Pentium4 CPU, 2 GB RAM, 1.0 TB SATA disk, onboard Intel graphics).
And KDE 4.7 is running exceptionally well on a generic slim desktop at work (2.0 GHz AMD Sempron CPU, 2 GB RAM, 80 GB SATA HD, nVidia GeForce 9400 GT powering 2 1280x1024 LCDs).
Spread across a range of Linux distros (Debian, Kubuntu, Arch) and FreeBSD.
You'd think after all these years, this FUD would end ...
the only problem with your analisys is that you must be running KDE 4 with composite enabled.
To compare it to both systems, you have to disable it entirelly.
Also e17 although it does fancy shadows, it doesnt provite composite except enabling the "bling" module.
to me KDE4 runs amazingly well with a 1ghz cpu and an intel 945.
also on my GF's eeepc.
maybe its just you !
PS : ( but i understand you, because just switching from opensuse 11.4 to gentoo + git xorg made a complete diference in performance on my desktop)

If you don't use its advanced features, then it is essentially no different on the surface (the UI) to other desktops such as XFCE. Except of course that underneath the UI KDE4 has the abstraction layers Phonon and Solid which provide applications with a more stable API than any that XFCE provides. Except of course that it provides a better environment under which to run KDE apps and Qt apps and an equivalent environment under which to run GTK apps compared to XFCE. Oh, and except of course that the KDE Software Collection, as a whole, is far far in advance of the XFCE default application set.
Since, if you don't use its advanced features, it is superficially no different to other desktops, except that it has better desktop applications (Dolphin, Okular, Gwenview, K3B et al), why not simply run it and enjoy it as such? Why do you feel a need to complain about it, and risk having rocks thrown at you, simply because it does in fact have advanced features which you don't happen to use?
Why not simply let advanced users use the advanced features, and be done with it? Live and let live.
KDE3 is not faster than KDE4, BTW, in fact KDE4 can use GPU hardware acceleration, such that it can even run on low-powered mobile phones and tablets using OpenGL ES. Also bear in mind that KDE3 relies on some technologies which are defunct and no longer supported, such as Qt3 and aRts.
