Attaching the detailed results of a CacheGrind analysis.  Here are the high-points (all of which were expected):

* The last level data cache miss-rate improved 12% (from 4.9% to 4.3%).
* The first level data cache miss-rate improved 14% (from 5.5% to 4.7%).
* The additional code caused the instruction cache miss-rate to get slightly worse (from .32% to .40%).

The last level cache misses are the most important.  Per the cachegrind docs, "an L1 miss will typically cost around 10 cycles, [and] an LL miss can cost as much as 200 cycles."
