Recently, I came across Julia, a high-level, high-performance dynamic programming language for technical computing. The language itself is interesting, but on the Julia website is are comparative language performance benchmark results. Julia is compared against several other common scientific computing languages, such as, Python, Matlab, R, etc.
The following micro-benchmark results are from a MacBook Pro with a 2.53GHz Intel Core 2 Duo CPU and 8GB of 1066MHz DDR3 RAM

I guess I see why node.js has been getting lots of attention for server side processing.
