Firefox Javascript Engine Becomes Single Threaded

Posted by Unknown on Wednesday January 25, 2012 @06:10AM from the software-engineers-hate-sharing dept.

An anonymous reader writes with news about work on Mozilla's Javascript engine. Quoting Mozilla engineer Luke Wagner's blog: "With web workers in separate runtimes, there were no significant multi-threaded runtime uses remaining. Furthermore, to achieve single-threaded compartments, the platform features that allowed JS to easily ship a closure off to another thread had been removed since closures fundamentally carry with them a reference to their original enclosing scope. Even non-Mozilla SpiderMonkey embeddings had reportedly experienced problems that pushed them toward a similar shared-nothing design. Thus, there was little reason to maintain the non-trivial complexity caused by multi-threading support. There are a lot of things that 'would be nice' but what pushed us over the edge is that a single-threaded runtime allows us to hoist a lot data currently stored per-compartment into the runtime. This provides immediate memory savings."

On second thought, let's not go to Camelot. It is a silly place.

You actually read the entire summary?!? Dude, I lost interest at "Javascript".
