I don't know what people have been doing, but now, using the
same config file as a week ago, I get a kernel that is nearly 10x
slower for disk operations.

	My Sun4/260 usually takes about 5 minutes to fsck it's 5 disks
(5 partitions, 2 of the disks are one ccd).  With Monday's Sup, it's
taking nearly 45 minutes.  The whole thing 'in use' is slow, too --- X
and launching applications is noticably slower.

	The new kernel also failed to run the news expire in 12 hours
(I had to kill it).  It normally takes 2 or 3.  It fell seriously
behind on unbatching (batches came in over the modem faster than they
were processed).  The system normally runs 200-300 batches/hour.   It
was doing less than 10.

	I'm going to include my config file at the end of this post.
I noticed also that the kernel ballooned in size by about 100K in one
week.  Is this the nfs v3 code, or something more evil?

	Whatever is slowing the whole process down SOOOO much is going
to stall my device driver work (I can't run that slow a kernel).
