> With the improvements to contrib/benchmark in LUCENE-2050, it's now
> possible to create compelling algs to test indexing & searching
> throughput against a periodically reopened near-real-time reader from
> the IndexWriter.
> Coming out of the discussions in LUCENE-1526, I think to properly
> characterize NRT, we should measure net search throughput as a
> function of both reopen rate (ie how often you get a new NRT reader
> from the writer) and indexing rate. We should also separately measure
> pure adds vs updates (deletes + adds); the latter is much more work
> for Lucene.
> This can help apps make capacity decisions... and can help us test
> performance of pending improvements for NRT (eg LUCENE-1313,
> LUCENE-2047).
