Thanks for providing the evaluation results. This shows nice improvements when huge pages are not used. My intuition is that using huge pages reduces the opportunity from function reordering.

Would you please clarify what specific performance counters are used in the measurement? For iTLB misses icache_64b.iftag_miss includes speculative execution but frontend_retired.itlb_misses does not.
