I didn't try things like "FreeBSD + ext2" or "Linux + ffs". I attached here results of the test I performed. For test I "gunzip"ped FreeBSD ports collection, in attachment You can find "scripted" output of "# time sh install.sh" for both systems. Also there are "dmesg" outputs. machine was THE SAME: read "dmesg", FreeBSD-3.3 + softupdates + "# tunefs -o time" + "flags 0xb0ffb0ff" (kernel was compiled with "-O2") Linux - RedHat-6.0 with out_of_box_kernel, just "# hdparm -d 1 -c 3 -m 16 /dev/hda", read "hdparm" output... even as non-native English speaker I know few other other words which begin with "f" :-) is "fast" the propriate one for "ffs" ?
