Hi rozcovo,

IMHO, this is not a computationally difficult task. It really boils down to first loading the reference data into a hash and, then, read a single input file and lookup into the hash. Quite simple. And since there is apparently only one data input file, I doubt that using threads will bring any performance benefit.
