As discussed in https://groups.google.com/d/msg/golang-dev/Na9XE6mcQyY/zbeBI7R-vnoJ Here is a static copy of the go/parser benchmark. I ended up using fancy encodings because the original parser.go had a number of `s scattered throughout which made it hard to embed the source directly. Curiously on my laptop this benchmark always scores roughly 10% higher than the standalone benchmark. This may be down to the generation of the fasta data set triggering the cpu governor to raise the cpu speed. However the benchmark is consistent with itself across multiple runs.
