Directory listing speed

[Michael Schuster]

Luciano,

a few questions come to mind:
- what are you doing with the output (> /dev/null?)?
- how are you measuring this?
- what else is the machine doing while you're doing your 'ls'?
- [you may have said so in an earlier message:] is the HW (including disk
infrastructure) comparable to the linux box?
- is this time you're reporting, while significant, the only issue you
have, or do you actually see something really show-stopping on that machine
(IOW, what problem are you trying to solve)?
- do you have comparable numbers in comparable directories?
- do you see any error messages or warnings in the logs?

you get the idea ... :-)
