How Ignition and TurboFan Revolutionize Node.js Performance
The article explains how V8’s new Ignition bytecode interpreter and TurboFan optimizing compiler, enabled by Chrome 57, eliminate previous JavaScript performance pitfalls—such as try/catch, let/const, debugger, generators, and async functions—allowing Node.js to achieve significantly higher runtime speed.
V8 engine is the backbone behind Node.js, and V8’s performance directly determines the performance of the Node.js runtime itself.
In previous performance‑optimization advice, keywords such as try, catch, let, const, debugger, as well as generator functions and async functions were considered performance killers; when these appear in a scope, the V8 engine cannot optimize the code at that location.
The good news is that these issues will no longer exist. Starting with Chrome 57, Ignition (the bytecode interpreter) and TurboFan (the optimizing compiler) are enabled by default, so the JavaScript language features once deemed performance killers can now be used confidently. After Node.js adopts Ignition + TurboFan, its performance is expected to improve markedly.
This achievement did not come easily; switching from Crankshaft to TurboFan is comparable to fitting a 250 km/h Formula 1 car with a new engine. Want to learn the challenges behind this transition? Click the original article to read more.
