  1. Nice talk! I’m intrigued by the various JITs that are now trying tracing on a much smaller scale. HHVM does it on a basic block level, Pyston on a bytecode level (with, as far as I understand it, plans to extend it to a somewhat larger scale).

    Is the benchmark that tries more and more megamorphic attribute lookups available somewhere?


    • Sorry for the delay — the benchmark is available here. For what it’s worth, I put together a similar benchmark that stresses a different “problem difficulty” axis (control flow diversity) which I didn’t end up presenting but has a similar performance graph.
