I have just upgraded from AMD Athlon 64 X2 5200+ to AMD FX 8350 Eight-Core 4GHz, the Handbrake video compression FPS went from 10 to 120-300. This makes for almost linear boost for GHz and number of cores.

Nothing newer on the topic? Given that 64-core nodes have become standard in high performance computing, and there are talks about 100s of cores on a single chip, the research may benefit from revision.

Love how this is old MIT work, with HN pointing to "stanford.edu"

This study is from 2010 (Linux kernel 2.6.35-rc5).

Yes, i am wondering how much this holds true with a recent kernel. Still interesting though!

illumos kernel is known to scale better.

Any references?

I'm not sure if anyone made a strict quantitative analysts. This is what I remember reading: http://gdamore.blogspot.com/2010/02/scalability-fud.html
