An exploration of improving Ruby's Foreign Function Interface (FFI) performance through JIT compilation demonstrates potential speed improvements over traditional FFI implementations. Using a proof-of-concept called FJIT, the author achieves performance comparable to C extensions while maintaining Ruby-centric development practices. The implementation shows promising results with benchmarks indicating more than 2x speed improvement over conventional FFI calls.
