Changing Vectors systematically to ArrayL
No progress yet.
I think my next move is to do what I did when trying to get KinoSearch
to write Lucene-compatible indexes:
1) Generate an optimized split-file format Lucene index from a
pathological test corpus.
2) Hack KinoSearch so that it ought to produce an index which is
identical

I might be the only one here that counts every wasted tick? :)
But it is not the synchronization I think is the big thief. A LinkedList

All I've added since then i
I think most of Vector (or Hashtable) references are leftovers from the
pre-Java Collections era, that's all.
I doubt we'd be able to get much juice out of move unsynchronized Java
Collections, although I'd like to see them for the same reason as Yonik.

Currently, buffer sizes for BufferedIndexInput and
BufferedIndexOutput are equals and have constant size of 1024 bytes.
When using a database for index persistence, it slowdowns performance much
because of relatively small buffer size. With JDBCDirectory and buffer
size increased from 1Kb to 16K

Hi Marvin,
Where are you with this? I also have a vested interest in seeing
Lucene move to using byte counts. I was wondering if I could help out.
Is the patch you pasted here the latest you have?
Cheers,

Does anyone have any numbers on the performance differences on such a
refactoring? I reckon it wouldn't be that hard to put together a
reasonably representative dataset and test before/after. Who's game?
