Michael McCandless commented on LUCENE-2871:
--------------------------------------------
OK -- I was able to index 10M docs w/ the new patch. And search results are
identical.
But the indexing time on trunk vs the patch were nearly identical -- 536.80 sec
(trunk) and 536.06 (w/ patch). But, this is on a fast machine, lots of RAM (so
writes go straight to buffer cache) and an SSD, using 6 indexing threads.
