FFS on FreeBSD does synchronous meta-data updates conservatively, : while EXT2FS on Linux is more aggressive about write-behind caching of : meta-data (therefore the meta-data in memory is out-of-sync for a longer : time with meta-data on disk.) The Linux approach is faster for bulk : directory operations, but -current FreeBSD does a bit to mitigate the Let me put it in another way: Linux feels faster for the day-to-day work. You usually don't copy large files very often. : difference by supporting an async option for mounts. FreeBSD IS faster : for copying large files (even the most recent Linux vs. most recent FreeBSD.)
