Bug ?: SCHED_4BSD VS SCHED_ULE

[Ian Lord]

Sorry about the rc.conf mistake, I should sleep more at night instead 
of typing stupidities :)

I was meaning
/usr/src/sys/amd64/config/MYKERNEL

I am running freebsd 5.4 amd64 version

Should there be a big improvement from running ULE ?, nobody reported 
the bug I have with it ?

Thanks
