OK tried it briefly with -o -F. Got 68 hits/sec! That's quite a remarkable
speed up from 13-15 hits/sec.
On a slower machine the speed up was only from 6 hits/s to 13 hits/s.
Switched back to sync tho. Too cowardly ;). Plus speed is not so critical
at the moment.
Well at least I know there's more juice on tap if I really need it...
Cheerio,
