"We wanted to find out just how well the Linux version of
Firefox faces up against its Windows equivalent, so we ran the
benchmarks from all three browser makers to make sure we got a full
range of results. Some specifics you probably want to know:
"* We used Firefox 3.0.6 running on Windows XP SP3 and Fedora
10. Both were running in 32-bit mode.
* Our test machine was a quad-core Intel Core 2 running at 2.66GHz,
with 4GB of RAM and 1.5TB of hard drive space.
* The three tests we used were: SunSpider, V8 Benchmark 3 and
Dromaeo (using "Recommended Tests").
* We have marked in red where Linux performance falls behind
Windows for a given test, and vice versa. In short, red numbers are
the ones that scored lower."
