Uwe Schindler updated LUCENE-1741:
----------------------------------
Attachment: LUCENE-1741.patch
Attached is a patch using the JRE_IS_64BIT in Constants. I set the default to
256 MiBytes (128 seems to small for large indexes, if the index is e.g. about
1.5 GiBytes, you would get 6 junks.
I have no test data which size is good, it is just trying out (and depends e.g.
on how often you reboot Windows, as Eks said).
> Make MMapDirectory.MAX_BBUF user configureable to support chunking the index
> files in smaller parts
