Dmytro,

Sorry the debug -g option did not help.

I have only noticed increased speed with 6 vs 5.4, but then again I am 
not using X, I use FreeBSD only for servers.

I noticed a slight lag at first and was not using the SCHED_ULE 
scheduler, but the 4BSD.

Removing debug -g and recompiling my kernel pretty much solved that.

Thanks,

Russell
