Aha, some observations :

- large number of files : some OSs write meta-data synchronously,
this means that operations on large directories are 100 times
slower than on , let's say Linux
- RAID-1 mirror - this slows down write performance, because the data must
be delivered to TWO disks . The slowdown may not be great, but it is still
a slowdown. ( read may be faster, depending on the RAID-implementation inteligence )

This "benchmark" is a bad joke anyway ...
Somebody make a real one or just stop this thread.
