At various stages in the KDE 4 evolution kwin did indeed have poor performance at some releases. Sometimes this was due to kwin itself, and at other times it has been due to kwin exposing deficiencies in underlying drivers that have been dormant for years (with no programs actually exercising the drivers in that way).
Lately though, it has picked up again. On my modest Athlon 64x2 system, kwin with compositing (Arch Linux, KDE 4.6.3) is faster and more responsive than Windows. Some time ago I used to have to temporarily switch off kwin compositing (Shift + Alt + F12) if I wanted to view anything but the smallest of videos smoothly, but lately that has not been necessary.
