Try plotting response times as a function of hit count. My guess is that your 99 and 99.9 percentiles are for really high hitcounts, which will take a long time as they all needs to be scored. Alternatively, if it is easier for you, just check the queries in the 99+ percentiles manually and see if they hit a lot of documents. If your response times grows about linear (with a bump at one point, due to switch from sparse to non-sparse docset) as a function of hitcount, there is not much about it besides sharding, with the current single-threaded processing of lucene queries. - Toke Eskildsen --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
