see you're trying out a 6.3 beta, any chance you could try out a 7.0
beta instead? Also, consider switching to "options SCHED_ULE" in the
7.0 kernel rather than "options SCHED_4BSD".
I tried SCHED_ULE, but got no difference:

You have a lot of free memory. Maybe you can wait a little to let it fill
the cache or let it use more buf's. This could explain that the system is
spending a lot if time in 'system'.
