Date Sun, 29 Jul 2007 01:00:52 GMT

]

Michael McCandless updated LUCENE-967:
--------------------------------------

    Attachment: LUCENE-967.take2.patch

New rev of this patch.  Only real change is to reduce overhead
(slightly) of benchmark framework by pre-building array of PerfTasks
instead of creating new iterator for each document.

> I've been looking at performance improvements to tokenization by
> re-using Tokens, and to help benchmark my changes I've added a new
> task called ReadTokens that just steps through all fields in a
> document, gets a TokenStream, and reads all the tokens out of it.
> EG this alg just reads all Tokens for all docs in Reuters collection:
>   doc.maker=org.apache.lucene.benchmark.byTask.feeds.ReutersDocMaker
>   doc.maker.forever=false
>   {ReadTokens > : *
