I think you're reading it right on the plain Hello World benches, but the in the HAML and SASS benches node is already 2 to 4 times faster with no concurrency. I think this speaks a lot for the impressive speed of V8. HAML/SASS are originally Ruby libraries, and carry a few years of experience on their backs, unlike their javascript versions. These V8 numbers are even (far) more impressive: http://attractivechaos.github.com/plb
