Chrome browser Beta 33 background JavaScript compilation increases performance

When it comes to optimizing web browsers, most of the firms behind popular browsers like Firefox and Chrome are always out to optimize the browsers for the best possible performance. Google has announced a tweak to the Chrome browser this week that will make web apps run faster on the browser than they did before.

The optimizations for web apps are available in the latest Chrome beta version 33. The new feature is dubbed concurrent compilation and promises faster and smoother optimized versions of the code the browser runs. Google says that the concurrent code compilation is a step towards reducing latency for the browser user.

The tweak has to do with JavaScript performance, which is a big deal since web apps and web pages commonly use apps written in JavaScript. Google's concurrent compilation takes advantage of multicore processors inside most computers today.

Chrome converts the JavaScript code for pages and apps into a faster native code during optimization. In the past, that optimization on Chrome was done by pausing the execution of the code while it was complied into an optimized version. The optimization in the beta Chrome takes place in the background without pausing the execution of the code, increasing performance.
