Chrome and Firefox 3.5 Memory Usage

Problem. You are interested in how the Google Chrome 3.0 Dev, Firefox 3.5 RC, Safari 4.0 for Windows, and Opera 10b web browsers manage memory on the Windows Vista operating system over moderate usage, such as with 150 top web sites. These numbers can be measured but there are complexities involved in measuring memory. Solution. Here we look at a program that simulates a user visiting the top 150 web sites from Alexa from the command line, with visits occurring at short but varying intervals in many tabs.

Results

Here we see the results of the experiment when performed as described above. During the experiment, 384 memory checkpoints were taken, which amounts to 1152 seconds or 19.2 minutes. Google Chrome posted the highest maximum memory usage when all chrome.exe processes were summed, reaching 1.18 gigabytes, while Firefox posted the lowest maximum memory levels of 327.65 megabytes. This means Firefox used 73% less memory during peak periods.

LOLOLOL!

Para mim Firefox sempre foi o melhor. E agora no 7, tudo a rular. Não percebo todo aquele tesão à volta do Chrome...

Eu cá não tenho chatices com o Opera, tests are meaningless, depende da experiência do utilizador com o browser.

Portanto, passar duma gestão de memória pior que a do IE para usar pouca memória é motivo de orgulho, i guess. Pa, cada um sabe de si, mas pra mim Firefox, meh... Uso no Ubuntu e já chega. Mas suspeito que mesmo aí vou passar para o Chromium em breve

quando houver uma base de plugins tao grande e ser tao costumizavel quanto o firefox, logo mudo

Ya, concordo com isso. Eu achei o chrome muito bom, rapido e tal. Mas os plugins do firefox <3

O Chrome é feio.

Chrome <3

quem diz é quem é pá

^2. Só tenho pena que alguns plugins não sejam compatíveis com o Opera.
