Subject [jira] Commented: (LUCENE-2662) BytesHash
Date Fri, 01 Oct 2010 12:29:33 GMT


Michael McCandless commented on LUCENE-2662:

I indexed 10M 1KB wikipedia docs, single threaded, and also see things a bit faster w/ the
patch (10,353 docs/sec vs 10,182 docs/sec).  Nice to have a refactor improve performance for
a change, heh.

The avgUsedMem was quite a bit higher (1.5GB vs 1.0GB), but, I'm not sure this stat is trustworthy....
I'll re-run w/ infoStream enabled to see if anything looks suspicious (eg, we are somehow
not tracking bytes used correctly).

Still, the resulting indices had identical structure (ie we seem to flush at exactly the same
points), so I think bytes used is properly tracked.
