Simon Willnauer updated LUCENE-2662:
------------------------------------
Attachment: LUCENE-2662.patch
Next iteration - seems to be very close!
I have applied the following changes:
* introduces a AtomicLong to track bytesUsed in DocumetnsWriter,
TermsHashPerField, ByteRefHash and RecyclingByteBlockAllocator
* Factored out a BytesStartArray class from BytesRefHash that manages the
int[] holding the bytesStart offsets. TermsHashPerField subclasses and manages
the ParallelPostingsArray through it.
* remove remaining no-commits
* made RecyclingbyteBlockAllocator synced by default (we use synchronized
methods for it now)
I run a quick Wikipedia 100k docs benchmark against trunk vs. LUCENE-2662 and
the results are promising.
|version|rec/sec|elapsed sec|avgUsedMem|
|LUCENE-2662|717.30|139.41|536,682,592|
|trunk| 682.66|146.49|546,065,344|
I will run the 10M benchmark once I get back to this.
