The time required to JIT compile code apparently has a big effect on web browser JavaScript performance. Web pages often have a lot of cold code that isn't run often.

JavaScriptCore is getting a new fast interpreter that will be the first choice way to run code that hasn't proven hot: http://trac.webkit.org/changeset/108309

Well there certainly is a lot of scope to make a faster interpreter, as eg according to http://news.ycombinator.com/item?id=1187901 the Luajit interpreter is faster than compiled v8...

I'd be surprised if that's still true today. V8 used to be consistently slower than LuaJIT, but has caught up since then.

Would be interested in an update, but was actually referring to Javascript interpreters, which were very slow.

What makes you think it has caught up?
