What are soft updates?
Okay, this explains the write part, but not the "no read caching", or
"too small to be noticeable". I tried it again without luck, if I read a
file, and then re-read it (file, directory, whatever), the disk gets
accessed again. 
I take as a reference point the linux machine I'm working on where, if I
do "du", first reads the disk (slow) and the 2nd time it goes at least
2x (some cache misses, I guess ;). Under NetBSD if I do du from a
(relatively) small directory twice it still reads all the data back from
disk...? 
Maybe a fstab misconfiguration? Puzzles me....
