My experience - on ntfs ... i have a directory of approx 10thousand 5 minute 
log files of me playing telnet based muds ... *snicker*
i can grep them all (each about 10-20k) in a few minutes ... (9 grep 
commands because command line expansion limitations :P) - really preformance 
drop is not that noticible.  Except in one area.
cd'ing to the directory in the first place - can take a minute or more, 
subsequent cd's are fast, but it seems like its caching all the filenames in 
the directory for faster access.

Anyway ... theres a 'pseudo-data-point'

Regards,
Gareth
