IE8 consumes 52% more memory than IE7, it seems
Craig Barth, chief technology officer at Devil Mountain Software, a Florida-based maker of PC performance testing software, said that the Beta 2 version of IE8 consumes 52 per cent more memory than its predecessor, IE7, and uses almost three times as many threads.
He said that IE8 was more bloated than a three week corpse of a hippopotamus that had eaten Texas. Barth tested IE8 Beta 2, IE7 and Firefox 3.0.1 in a 10-site scenario that involved media-rich domains such as boston.com, channel9.com, cnet.com, infoworld.com, nytimes.com and others.
IE8 Beta 2 had grabbed 380MB of memory on the 2GB-equipped system running Windows Vista, while IE7 accounted for 250GB and Firefox 3.0.1, the most-recent version of the open-source browser, had taken 159MB. The browser did a little better when run under Windows XP, each browser consumed slightly less memory than in Vista; IE8 Beta 2, but not by much.
