No, it's not true.

Running on a variety of machines makes certain changes noticed which
would otherwise be missed. A 'bad' change which slows booting by 1
second on i386 might stand out as a 30 second slowdown on sun3...

Now, it may be true that NetBSD doesn't use all of the optimizations
that are available on every platform - in that case, feel free to
contribute suggestions of where improvements can be made.

It sounds like getty may have been swapped out, in order to free up RAM
for another task. Check how much RAM you have, (16?) and look at the
'Capacity' column in the output of 'pstat -s' to see how much swap is
being used.

When you exit, and getty wakes up, it would be swapped in, and depending
on the speed of your disks, that could take a second (or more).
