WimMark I for 2.5.64

WimMark I for 2.5.64

[Joel Becker]

WimMark I report for 2.5.64

Runs:  1430.06 1194.90

	WimMark I is a rough benchmark we have been running
here at Oracle against various kernels.  Each run tests an OLTP
workload on the Oracle database with somewhat restrictive memory
conditions.  This reduces in-memory buffering of data, allowing for
more I/O.  The I/O is read and sync write, random and seek-laden.
	The benchmark is called "WimMark I" because it has no
official standing and is only a relative benchmark useful for comparing
kernel changes.  The benchmark is normalized an arbitrary kernel, which
scores 1000.0.  All other numbers are relative to this.
	The machine in question is a 4 way 700 MHz Xeon machine with 2GB
of RAM.  CONFIG_HIGHMEM4GB is selected.  The disk accessed for data is a
10K RPM U2W SCSI of similar vintage.  Unless mentioned, all runs are
on this machine (variation in hardware would indeed change the
benchmark).

Interesting, but a couple of questions:
Which arbitrary kernel scores 1000.0?
Is the score very consistent on that kernel and machine?  (what kind of 
max/min scores do you get?)

	The scores for a particular kernel are pretty consistent.
That's the intent.  Some kernels I'll have data for multiple runs, and
you can see the variation between runs.
