Browser Shootout – Part III

August 3rd, 2009

Quickly on from Part I and Part II, here is part three of the great browser shootout. The browsers we are looking at are:

All the tests are done on a fully updated Windows 7 RC on a IBM ThinkPad R52.

The first tests I do is to start up the browsers and check the time till they are fully open and I am able to view a site. All the browsers were set to a blank home page so that this would not affect the load time. After they are open, I check the memory usage.

Then I load one by one the following sites:

For gmail and hotmail, I don’t measure the time to load the login page, but rather the time from login to the time I can see the inbox. In the case of hotmail, this is not the inbox but the main “activities” screen.

All the times taken before this are in seconds and you may take +/- 1 second error.

Following this I run the Acid2 and Acid3 tests. Considering that all the browsers here are Acid2 compliant, only the Acid3 has any meaning. Acid tests are a measure of the browsers ability to support HTML and CSS standards as defined by the W3C. Acid3 requires support for JavaScript as well.

Then I loaded up four different JavaScript test sites. At this point I again checked the memory usage. For Chrome and Internet Explorer 8, I will give the total usage of all the processes in memory.

The JavaScript tests were then run:

The JavaScript test from the V8 Browser comparison is a numerical score – higher the better; the other JS comparisons are in milliseconds – lower the better. The mootools test is actually a test to compare different JavaScript libraries, Mootools own as well as JQuery, Prototype, YUI and Dojo. This test acts as an indicator of real-world usage, since many sites use one of these libraries to run their JS. Note: IE8 failed the Dojo test completely.

Without further ado, here are the results of the tests.


Of course, IE8 handily wins this one. The slow time of Opera may be due to the fact that it is still in beta.


This is a logarithmic scale, otherwise it would be difficult to show the usage. IE8 is a huge memory hog, using 824MB when loaded, nearly 4 times the usage of the next highest which is Safari 4. Chrome easily wins this with a usage of only 127MB at max.


Most sites load pretty much the same on each browser, except on IE8 which consistently takes more time than the other four. Even hotmail, Microsoft’s own, is fastest in Firefox! Gmail also loads fastest in Firefox, but only by one second, well within the margin of error. Overall, Firefox comes in handily in first place, followed by Chrome and Safari 4 almost neck and neck. But these three browsers are easily the fastest and the difference in times to load these sites is so negligible in real usage, you can’t tell the difference.

The Acid3 test is very close. Opera, Safari and Chrome all do the 100/100. Firefox gets 93, but IE8 gets only 20! Although there is a problem with Chrome where you may see a “Linktest Failed” for a few seconds even after everything is complete until the page clears up to meet the reference.


The v8 suite is Google home-grown to torture test the JavaScript engines of the browsers, but considering the lead that Chrome has over the other browsers, one wonders if it is actually designed to highlight Chrome, considering the other JS tests don’t show such increases.


Again this graph is a logarithmic scale. All the times are in milliseconds. Here you find that IE8 is visibly the slowest in all tests, while Firefox, Chrome and Safari all are bunched together. If you go in for specifics, except for the SunSpider test (won by Chrome by a short head) and the Prototype test (won by Opera surprisingly), Safari 4 wins all the JS tests – whew!

So that’s the end of the tests. Finally, it comes out that all the browsers are pretty much equal when it comes to performance, except IE8. But even IE8 is head and shoulders above IE7 and IE6, so you should upgrade to this even if you are not willing to move to any alternative browser.

Which browser do I use? Primarily, Firefox because of the extensions I use – but I often use Chrome and Safari. I’m personally not a fan of Opera but that’s just me – it’s a very nice browser. Of course, there are still some sites which are nothing but IE compatible – so I still haven’t gotten the icon out of my quick launch.

Do drop me a line with any questions or queries.

    Internet Explorer 8 is very good because it is as stable as Opera. I hate the previous versions of IE like IE6 because it hangs frequently. “
