Precompiling Ruby scripts - Myth and Fact
summary
Ruby 2.3 adds precompilation primitives for RubyVM::InstructionSequence and provides methods like InstructionSequence#to_binary and load_from_binary; a sample controller, Yomikomu.gem (with kakidasu for baking binaries), implements multiple storages and lazy loading. Microbenchmarks show up to 5× faster repeated requires but compiled binaries swell ~5×; a Rails boots test halves parse/compile time yet only slightly trims overall startup because other work consumes ~60–70% of time. Precompilation helps some hotspots but is not a silver bullet.
