Robert Muir commented on LUCENE-2167:
-------------------------------------
bq. Here are the results on my machine (Sun JDK 1.6.0_13; Windows Vista/Cygwin;
best of five):
This is really cool, I think its a great benchmark to know, I played with it
and saw similar results.
* For Lucene Tokenizer-ish (forward-iteration) purposes, JFlex is quite a bit
faster than RBBI for unicode segmentation.
* Supporting unicode segmentation in StandardTokenizer doesn't slow it down in
comparison to the current implementation.
* The script detection/delegation in ICU doesn't really cost that tokenizer
much; though, the benchmark is reuters, and it cheats for Latin-1 (see bottom
of ScriptIterator.java).

> It would be really nice for StandardTokenizer to adhere straight to the
> standard as much as we can with jflex. Then its name would actually make
> sense.
> Such a transition would involve renaming the old StandardTokenizer to
> EuropeanTokenizer, as its javadoc claims:
> bq. This should be a good tokenizer for most European-language documents
> The new StandardTokenizer could then say
> bq. This should be a good tokenizer for most languages.
> All the english/euro-centric stuff like the acronym/company/apostrophe stuff
> can stay with that EuropeanTokenizer, and it could be used by the european
> analyzers.
