I now did this on 5.4-STABLE and I cannot observe any difference.  The
lags still happen in the same way.  The only difference seems to be that
 with PREEMPTION, at and shortly after boot, response seems to be
actually worse and from harddisk noise it doesn't seem to load stuff in
one go but in "chunks" (at least that's how it sounds).  That normalizes
after a while, though.  Weird.
