Sam Allen from DotNetPerls.com has tested the most recent web browser versions to find out, which one of them consumes the most and least memory.

Usign script help, he has loaded 150 the most popular sites as per Alexa.com and monitored results.

Results:

--- Maximum memory used --- Peak memory usage measured during experiment. Chrome: 1216.16 MB [Largest] Firefox: 327.65 MB [Smallest] Opera: 554.11 MB Safari: 517.00 MB --- Average memory used --- Average of all memory checkpoints throughout experiment. Chrome: 543.83 MB [Largest] Firefox: 166.82 MB [Smallest] Opera: 347.45 MB Safari: 319.44 MB --- Final memory used --- Figures taken after all tabs were closed at end. Chrome: 109.49 MB Firefox: 106.66 MB [Smallest] Opera: 441.49 MB [Largest] Safari: 349.62 MB

Firefox 3.5 also had the best average memory usage figures, meaning that it may consume the least memory of these browsers when used for the Alexa sites as tested in the benchmark. Finally, Chrome and Firefox posted the best memory figures at the end of the browsing session, with Opera consuming 4.1 times more memory than Firefox at the end of the test.
