> Project: Tika
> Issue Type: Bug
> Components: languageidentifier
> Reporter: Toke Eskildsen
> Assignee: Chris A. Mattmann
> Fix For: 1.8
>
>
> The distance calculation for language profiles creates a Set of Strings with
> each call and performs hashtable lookups for all those Strings. This patch
> creates and caches compact structures that are iterated sequentially. The
> result is a factor 2 speed up (see the performance test in
> LanguageIdentifierTest).
