The extra memory usage, though, is worth it the first time you don’t have to reopen 15 tabs after some Flash game… er, important research site crashes your entire browser. If you work with a lot of open tabs and windows, you’ll want to keep an eye on your memory usage all the speed of Chrome isn’t worth anything if you use up your RAM and start using virtual memory. Firefox used 172MB of RAM to open the five sites Chrome required more than 275MB. As a simple test, I opened the same five sites in Chrome and Firefox 3.5, and compared the total real memory usage in Activity Monitor. The downside of treating each site as a separate process is that you can chew through memory in a hurry. JavaScript tests aren’t the only measure of performance, of course, but these results back up the perception that Chrome is a speedy browser. The remainder of the browsers, were much further off the pace, with scores ranging from 2x to 10x worse than Safari and Chrome. Safari and Chrome, both built on WebKit, basically tied for second on both tests. Peackeeper browser benchmark, another JavaScript-based test.īased on these tests, the fastest browser of the bunch is SunSpider JavaScript Benchmark attempts to measure real-world JavaScript performance, using features that sites are using today. I ran eight browsers (Firefox 3.5 and 3.6b4, Safari and WebKit, OmniWeb, Camino, Opera, and Chrome) through two different performance tests. In this case, though, the numbers back up the perception. User perception can be more important than actual measured speed in a browser, and the perception in my time with Chrome is that it’s fast. Ask for a new window or tab, and it appears instantly. Even little things, like dragging a tab, feel much more responsive in Chrome than they do in Firefox. It feels fast because the interface reacts quickly to your actions, and page loading starts seemingly immediately after entering a URL. SpeedĬhrome is a very fast browser, both in subjective feel and objective performance tests. If you prefer to see text, too, you can add it by Control-clicking on a site in the bookmarks bar and choosing Edit from the contextual menu.
