My feeling was more some sort of scheduler problem, with apps being
randomly starved. As long as you stayed in the same app everything was
very fast, trying to switch or launch a new app would either be
reasonably fast of slow as hell. Starvation was not linked to any
particular app, more (like Ivan noted) to launch ordering.
I never noticed any particular load peak that could explain the
slowdowns. And this box had 256 MB which is not bad for its generation
and the only reason it can still be used.
