However, there seems to be an issue on that page: on Win8.1 x64 and Firefox 32.0.3 I get constant CPU of between 25-60% when it's loaded (I'm on a i7 Haswell CPU with 6GB RAM, and I see my RAM usage creeping up by about 1kB every couple seconds as well).
On Chrome 37.0.2062.124, I see the RAM usage creeping up in the same way, but CPU is low.
