Background Javascript Compilation Boosts Chrome Performance

Posted by timothy on from the processing-processing-processing dept.

kc123 writes "The latest version of Chrome includes improvements in JavaScript compilation, according to the Chromium blog. Historically, Chrome compiled JavaScript on the main thread, where it could interfere with the performance of the JavaScript application. For large pieces of code this could become a nuisance, and in complex applications like games it could even lead to stuttering and dropped frames. In the latest Chrome Beta they've enabled concurrent compilation, which offloads a large part of the optimizing compilation phase to a background thread. The result is that JavaScript applications remain responsive and performance gets a boost."

    Nope. That's the Just In Time part of the JIT. Javascript can't be (efficiently) compiled to native code until the data types of function arguments are know. Since Javascript is a dynamic language, the types can't be known until the function is actually called.

    Do not block the UI thread.
