anyway something get changed between FreeBSD 6 and 7.

as i changed this on quite loaded server from 6.3 to 7 - general 
throughput increased well. tasks are done much faster.

on on my laptop it's the same, but interactive delays was much lower on 
6.3

is it possible to turn "old mode" on FreeBSD 7. on my laptop interactive 
performance is more important.
