In short: SquirrelFish Extreme is fastest by a whopping 35% over its nearest competitor, making WebKit the fastest browser once again. Let’s see how the numbers come out.
SunSpider running from the command line (to ensure the test is as pure as possible) was used for this test. My test system is a 2.4GHz iMac.
These graphs are shown in runs per minute for clarity. Longer bars are better.

Dromaeo on Windows
As you can see, Firefox and WebKit smoke Google Chrome on this benchmark. WebKit comes out slightly ahead, so we need another benchmark to clear things up. Once again, Dromaeo, but on OS X now.
The full timings for these benchmarks are here:
- Google Chrome Nightly Windows – 13478.20ms (Total)
- Mozilla Firefox Nightly Windows – 7779.40ms (Total)
- Safari WebKit Nightly Windows – 7586.80ms (Total)
Dromaeo on Mac OS X
Full timings for these benchmarks are here:
- Firefox Nightly on OS X – 6648.20ms (Total)
- WebKit Nightly on OS X – 4387.20ms (Total)
- The Windows benchmarks ran on different test hardware from the Mac OS X and engine benchmarks.
Winner: WebKit + SquirrelFish Extreme
SquirrelFish Extreme wins this evolutionary cycle. Stay tuned for more coverage as Google, WebKit and Mozilla prepare their next moves.
