Matthew, there are changes in 2.6.26-rc1 that might affect your
workload with SLUB:

http://git.kernel.org/?p=linux/kernel/git/penberg/slab-2.6.git;a=commitdiff;h=c124f5b54f879e5870befcc076addbd5d614663f

I would appreciate any updates where we currently stand with the
SLAB/SLUB performance regression on your TPC test. Thanks.
