To all,
It appears I have found a defect in my testing. Generally, the procedure has been something like:
create filesystem
mount filesystem and set owner/group
run benchmark
alter some condition (CPU speed or IRQ routing)
re-run benchmark
compare results
The second run is contaminated by caching effects from the first run. This accounts for the roughly 5% speedup I saw after enabling explicit IRQ routing. Once I corrected this oversight, the difference became statistical noise.
My apologies to all for this red herring.
