Faster than C? Parsing Node.js Streams!
summary
A pure-JS MySQL parser reaches parity with libmysql C bindings and shows a 2x improvement in parts (benchmarks jump from ~350k to ~450k rows/sec). Development uses benchmark-driven development, heavy data collection and R/ggplot2 analysis, and concrete hacks like buffer whole packets to reduce state and generate per-query row functions with eval; the implementation is open source, measured, iterated, and exposes V8 heap/GC behavior that explains intermittent slowdowns.
