I venture to guess that the different versions of KDE were built with
different hardware in mind. Therefore, it's natural to expect that KDE has
matured (read: gotten bloated). Personally I run KDE 3.4 on 256 MB of RAM
with great convenience. Have you considered a more lightweight KDE desktop?
I suspect that there are KDE derivatives which would be snappier. Also,
remember that KDE can be easily customised to improve performance. I have
seen various pages about this. Here is another relevant page:

Check to see (e.g. using KSysGuard or top) if some off process is slowing
down (CPU) your more modern machines or eats up a lot of RAM, which leads to
paging.
