Chrome gets new mid-tier compiler: Maglev

We’re bringing a new mid-tier compiler to Chrome. Maglev is a just-in-time compiler that can quickly generate performant machine code for all relevant functions within the first one-hundredth of a second. It reduces overall CPU time to compile code while also saving battery life. Our measurements show Maglev has provided a 7.5 percent improvement on Jetstream and a 5 percent improvement in Speedometer. Maglev will start rolling out in Chrome version 114, which begins release on June 5. Let’s hope making benchmarks run faster also makes actual websites load faster.
