The ext filesystem is slow if you meter the right times.
If you e.g. untar a linux kernel tarball and just take the time
GNU tar runs, you have a time but you don't know the related action!
If you do this, disk I/O (with a few exceptions) will typically start
after GNU tar exited.
If you like to compare, you could either use star (that by default calls
fsync(2) on avery single file after extracting) or pull the power cord
after GNU tar finished and then check after a reboot ;-) On a ext filesystem,
star extracts 4x slower in default mode compared to star -no-fsync
I have no times for reiserfs, but it may be that the numbers look completely
different if you get a time for a known action.
