No, you don't understand. It has nothing to do with "ls /dev".
Many programs need to search through /dev. That includes lilo, the whole procps package, stuff related to the talk daemon, etc.
That's not even the worst of it. Every time you open a pty, you need access /dev. Every time you want /dev/null or /dev/zero, you access /dev.
The result: general system slowdown. You can't point a finger at the problem ("we lost 23 seconds RIGHT THERE because /dev was slow") but you suffer anyway.
Hey, Linus! It looks like a latency problem.
