4.2 scheduler

[John Tupper]

*** nothing cute here ***

We (not Wang Institute, a different we) recently switched from BSD 4.1 to
BSD 4.2. We have found 4.2 to be SLOWER than 4.1 by alot!

Disk io is faster, but cpu utilization seems to be way down. Sometimes
our vax750 will act loaded when there's only one process running (several
others hanging around doing nothing).

As far as I know we have the original 4.2 (have there been updates?).

Any help on the following questions would be appreciated.

	Has anyone else experienced the same thing (and what did
	you do about it).

	Are the different releases (updates) of 4.2?

	Is there any tuning we can perform to the kernel to speed
	things up?

Many thanks for whatever help you can offer.
