Mozilla Unleashes the Kraken
An anonymous reader writes "Mozilla has released the first version a new browser benchmark called Kraken. Mozilla's Robert Sayre writes on his blog, 'More than Sunspider, V8, and Dromaeo, Kraken focuses on realistic workloads and forward-looking applications. We believe that the benchmarks used in Kraken are better in terms of reflecting realistic workloads for pushing the edge of browser performance forward. These are the things that people are saying are too slow to do with open web technologies today, and we want to have benchmarks that reflect progress against making these near-future apps universally available.' On my somewhat elderly x86_64 Linux system Google Chrome 6.0.472.55 beta completes the Kraken benchmark in 28638.1 milliseconds, Opera 10.62 completes it in 23612.4 milliseconds, and the current Firefox 4 nightly build completes it in 19897.5 milliseconds."
For this particular Slashdot page right now, with both browsers opened fresh for it, Firefox 4.0 beta 6 uses 23 megabytes less resident memory than Chrome 5.0.375.125 does. It also uses about 1800 megabytes less virtual mapped memory, not that that matters nearly as much, but it's a big number in difference.
Epiphany 2.30.2 uses 11 megabytes less residential still, but about as much virtual as Chrome.
Galeon 2.0.7 uses about the same residential memory as Firefox and about twice as much virtual.
Midori 0.2.6 uses 5 megabytes less residential than Firefox, and about 1850 megabytes more virtual.
Arora 0.10.2 uses about twice as much residential memory as Firefox, and about twice as much virtual.
Dillo only needs 11 megabytes to render the page, but that doesn't have JavaScript and only shows a handful of comments without being able to get more.
Fennec 1.0 uses about the same memory footprint as Firefox 4.0 Beta 6, despite being the small-device Mozilla browser.
What is your exact complaint about Firefox's memory use? Are you still experiencing the huge memory leakage and growth from the 2.0 series?
