Performance Comparison of Major Web Browsers

I just finished reading this article about performance comparison of major web browser by Jacob Gube and wondered if everything was said. Unsurprisingly, Internet Explorer is presented as the worst and slowest browser. By the way, I often consider that people tend to appreciate criticizing when talking about Microsoft products in general.

But in the case were the tests complete ? It talked about speed, CPU, and read access time. But nothing about memory consumption. I jumped on the gun, took a look at my dozen tabs opened on Firefox and opened them as well under Internet Explorer 8 (IE8) and Chrome.

As you can see, Firefox momory consumption is bundled inside a single process while IE8 and Chrome creates several processes with different memory consumption.

But after summing all results, I was astonished to see that Internet Explorer 8 is the best browser concerning memory consumption. The fancy Excel graphic below perfectly illustrate that fact.

There is no doubt that IE 8 requires less memory than Chrome or Firefox.

For the sake of fairness, here are the types of websites I used for the test. All of them are common sites I use on a day-to-day basis:
  • iGoogle
  • Two bugtrackers: Mantis and Jira
  • Two tabs concerned games on
  • A PHPMyAdmin and a MediaWiki pages
  • A page on my online game (MMOG): Star Wars Combine
  • A web page from the MySQL site, one from an online banking, one from a newspaper with forums, and that blog on
In my next post, I will maybe make performance and statistics reports about the number of crashes of each browser. ;)
