In terms of speed alone, Apple is taking some steps to position its Safari browser to pass Google’s Chrome. But Mozilla’s Firefox has been running a different race.
WebKit, an open source browser engine for rendering web pages, is used in Safari. It had been used in Chrome, but now Google uses an WebKit offshoot called Blink.
But InfoWorld points out a pertinent fact: FTLJIT is still fairly “experimental,” and, although available in Safari’s WebKit, “it’s not actually turned on yet.”
