This is probably not terribly useful information, but -

I bit the bullet and updated to HEAD two days ago.  Trying the system
out today, the first thing I noticed was that it seemed to start out a
lot faster - small applications (like 'dillo') would seem to load nearly
instantaneously, and such - but that might have been an illusion after
getting used to using NetBSD on a slow drive for a side project.  Then
after some intensive use, DragonFly would return to a normal-seeming
speed, and after yet more use, drag down to a crawl.

Specifically I've been doing 'make realquickrel', and it starts out
fine, but by the time it gets to 'makewhatis', it's only dragging along.

Opening another rxvt (so that I could run 'top' and see what's going on)
took about a minute in total.  'top' does not show 'makewhatis' using
much CPU - rather, it gets stuck in 'vlruwk' state for ages at a time.

Hmmm, it just finished.  By the looks of it, the other programs like
'make' and 'install' are sticking in 'vlruwk' quite badly too.

I haven't run into any problems along the lines of "file reported
missing when it's actually there" yet.
