Hi Eric, Thank you for your response!
On the old system, I changed to use docValues=true, and had better performance. But the searcher was not warmed before I measured it. Also the local disk was too small so I used an attached volume which turned out was a big cause of the slow retrieve. On the new system, I didn't use docValues=true, but used SSD, so the retrieve was much much faster. In both cases, the QTime were good. I will keep tuning the performance for sorting, facets, etc. Thanks and all the best! -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
