Chrome får bättre prestanda
Upp till 30 procent snabbare på Android
Google meddelar i ett blogginlägg att man lyckats göra sin webbläsare Chrome 10 procent snabbare under de senaste tre månaderna i Apples benchmark Speedometer 2.1. Samtidigt har man även förbättrat prestandan för Chrome på Android i samma test med hela 30 procent. Förbättringen för Android ska främst gälla high-end-enheter. Så här beskriver Google förbättringarna:
"Pointer compression is used to save memory in both V8 and Oilpan (the garbage collector for DOM objects). We made optimizations to how we compress and decompress pointers, and we avoid compressing high-traffic fields. Given how frequently these operations are done, it has a wide spread impact on performance. We also moved frequently accessed objects like JavaScript’s `undefined` to the beginning of the memory bases, allowing them to be accessed using faster machine code... Chrome on Android has always been optimized for a small footprint, but the Android ecosystem is diverse and contains devices with varying levels of capabilities. To maximize the performance of Chrome on high-end devices, we are now targeting them with a version of Chrome that uses compiler flags tuned for speed rather than binary size."
