Can anybody enlighten me why LOCK and UNLOCK operations show different
performance depending on the size of the file? I always believed that
these two operate on some kind of semaphore attached to the file (gufd
or whatever internal structure). Does UNLOCK trigger some kind of post?

Lars (are we talking about MPE FLOCK/UNLOCK or POSIX range locking?)
