OK, I've isolated (magnified) the effect with a test I just checked in. Indexing documents directly at the UpdateHandler was 85% faster before the latest lucene update.
Run the test like this: ant test -Dtestcase=TestIndexingPerformance -Dargs="-server -Diter=100000"; grep throughput build/test-results/*TestIndexingPerformance.xml To run on an older trunk version, just copy over src/test/org/apache/solr/update/TestIndexingPerformance.java src/test/test-files/solr/conf/solrconfig_perf.xml I had a throughput of 10946 docs/sec before the lucene update, and 5849 after. -Yonik http://www.lucidimagination.com On Sun, Aug 9, 2009 at 12:10 PM, Yonik Seeley<[email protected]> wrote: > On Sun, Aug 9, 2009 at 12:01 PM, Grant Ingersoll<[email protected]> wrote: >> Or bite the bullet and upgrade to the incrementToken() method. > > Right - I'm not sure if that would fix it or not - I haven't been > involved in the new Token attribute stuff... > I'm currently writing a basic indexing unit test that we can use to > measure this (the standard solrconfig does stuff that slows down > indexing a lot, but helps in catching bugs on edge cases by creating > many segments). > > -Yonik > http://www.lucidimagination.com >
