TruffleRuby runs Optcarrot 9 times faster than MRI 2. TruffleRuby is new optimizing implementation of Ruby. Optcarrot is a NESemulator. MRI 3 targets to run Optcarrot 3 times faster than MRI 2. We willexplore the techniques which allow TruffleRuby to achieve high performance inOptcarrot. TruffleRuby runs Optcarrot 9 times faster than MRI 2. TruffleRuby is new optimizing implementation of Ruby. Optcarrot is a NESemulator. MRI 3 targets to run Optcarrot 3 times faster than MRI 2. We willexplore the techniques which allow TruffleRuby to achieve high performance inOptcarrot. We’ll discuss splitting, inlining, array strategies, Procelimination, etc.
