I was using a little script to warm up my file cache for Specweb runs
when Martin Bligh said that it might be a good test of your kmap
patches. I ran 8 greps in parallel (1-per-cpu) through a 10-gigabyte
Specweb file set which is on a RAID array. The RAID is how I can do a
cold run in 3 minutes 30 sec :). Each grep works on a disjoint set of
data.
Here's a run with the cache already warm:

You'll probably only care about greptime.total, and lockstat. The
network stuff is cruft from when I actually run Specweb.
Here's a cold cache run:

Here are warm and cold, without the kmap patches

I would give you oprofile data, but it appears that NMIs wreak havoc
on a certain vendor's hardware. When oprofile is compiled in, my box
gets quite unstable.
