Language relative speed is assessed by measuring speed of solving specific problem using specific algorithm implemented with most natural (idiomatic) tools available in given language.
The problem that is being solved by test programs is building a trie (a prefix tree) for Polish language dictionary (gz, bz2).
Most implementations use their respective hash-maps to link prefixes with tails.
All tests runs were performed with tcmalloc preloaded (if using it improved performance).
