One thing, why does 'ps aux' take about 5 seconds to complete, while
on FreeBSD it takes roughly 0.4 seconds? The ktrace output from ps
gave me a 1 Mb file. And, while printing the process entries, there is
heavy hard disk i/o, most likely this that causes the slow printing.
It looks like, from the ktrace output, that ps scans the /netbsd
image. But why so slow?
