The article linked is doing much more than benchmarking string operations. I'd even argue that string allocations are about as minimal as possible with the algorithms used. The C version takes this a little farther, but each of the other implementations are pretty similar. I don't disagree that benchmarks should be taken with a mound of salt though.
