DaMan writes "ZDNet picks up on yesterday's Firefox 3 beta 1 review by comparing the memory usage of Firefox 2 against the latest beta. The results from one of the tests is quite interesting, after loading 12 pages and waiting 5 minutes, 2 used 103,180KB and 3 used 62,312KB. IE used 89,756KB.""

    From the article:

    Both Firefox 2.0.0.9 and Firefox 3.0 b 1 were installed fresh using a standard install.

    FC 6 .. kernel 2.6.22.. Firefox 1.5.0.12 vs 3.0b1

    I created a new user, logged in and loaded up FF 1.5.. opened up 12 tabs and logged into these sites

    Here are the numbers for ff 1.5. The first line is when it loaded up with 12 empty tabs. The second line is the 12 websites loaded initially.. and the third line is 12 minutes afterwards

    I logged out, rm -rf ./.mozilla then logged back in and fired up FF 3.0b1.. same procedure, same 12 websites and 12 minutes of idling on them

      4231 perfume 20 0 254m 107m 40m S 1.3 28.5 2:27.26 firefox-bin

    CPU usage seemed to be much better with FF 3B1 as well.. not sure why the difference but everything was clean...
