There are a few more places where the lookup could be inserted, but I think these are the ones that will matter performance-wise.
Perf results in patch 3's log. Regarding the benchmarks: I'd have used SPEC06 but I don't have much time to get it to compile. Is there a guide on how to do so? Ideally I'd like to use the fedora image, which works very well. Thanks, Emilio
