Parallel and Thread-Safe Ruby at High-Speed with TruffleRuby
summary
TruffleRuby running on Graal/SubstrateVM uses partial evaluation and inlining to compile Ruby core and JIT across language boundaries, producing native code that hits up to ~8× Optcarrot vs Ruby 2.0, ~10× ERB, and 20–30× on some microbenchmarks. Arrays and Hashes gain thread-safe semantics by tracking when objects migrate from thread-local to shared and applying concurrent strategies (fixed vs dynamic storage) so single-thread speed stays native while scaling to tens of cores with comparable throughput to Java on NAS parallel benchmarks.
