Comments on: Opera 9.5 Optimizes JavaScript; Beats Firefox 3 http://cybernetnews.com/opera-95-optimizes-javascript-beats-firefox-3/ Technology News Sun, 22 Nov 2009 13:29:52 -0600 http://wordpress.org/?v=2.8.6 hourly 1 By: Ryan http://cybernetnews.com/opera-95-optimizes-javascript-beats-firefox-3/comment-page-1/#comment-137828 Ryan Mon, 12 May 2008 20:00:47 +0000 http://cybernetnews.com/?p=12550#comment-137828 <div class="commentquote"><a href="#comment-137768">Anonymous wrote:</a><blockquote>So, let me see if I’m clear here.

It is still a Beta version of the browser, and that has to be taken into consideration. Sure it didn’t run all of the tests, but if it did then it’s likely that it would have beaten Firefox on those, too.

StationStops is actually correct in several ways if you only look at browsers that have been released.

That’s a really good point, and excessive writing to the Flash drive can actually shorten the life of the drive.

Sure it's nice if a browser is fast, but you also have to look at how you work and what fits best with the way you work. For me FF works best for me and the way I work. However I have found one instance where Opera works better for me and that is a portable app to carry around on my flash drive; Opera@USB http://www.opera-usb.com/operausben.htm works great for this. In that instance FF lets me down due to too much writing to the flash drive which really makes it to slow to be usable. The fact that this new version breaks so much will probably keep me away from it for now. Thanks for the update on the browser speed wars though; it always interesting to see where the browsers are headed. Speed is not the only consideration when choosing a browser.

I guess the optimizations were done to help Dragonfly’s performance as well.

Opera scored 5853.6ms +/- 1.0%, while FF scored 5280.6ms +/- 6.0%. If you take the margin of error into consideration applying -1% to Opera and +6% to FF we get 5795.064 for Opera and 5597.436 for FF. No matter how you stretch the benchmark, FF takes the crown, but not by much anymore. You can definitely see the improvements in Opera's JavaScript engine thanks to PGO. BTW, I ran this on Penium M 1.5GHz with 1GB or RAM if it matters to anyone. Also, I upgraded my Opera installation to latest build from the first beta 2 build.

Opera broke their browser by optimizing it and now it's broken on some tests but on some tests it's faster than Firefox 3 which isn't broken on any tests and that translates to "Opera beats Firefox 3"? So, let me see if I’m clear here. Opera broke their browser by optimizing it and now it’s broken on some tests but on some tests it’s faster than Firefox 3 which isn’t broken on any tests and that translates to “Opera beats Firefox 3″?
