I'm testing solr search performance using LoadRunner the index contains 5M+ docs , about 10.7GB large. CPU:3.2GHz*2 RAM16GB The result si dispirited max:19s min 1.5s avg 11.7s But the QTime is around 1s (simple query without facet or mlt,just fetch the top 50 IDs) So it seems that XMLWriter is the bottleneck Am I right? Or is there anything i can do to improve the performance?
Are you limiting the results? Because if you are not writing even a tiny portion of those 10gb can take 11secs for sure. If you can please see the diference from writing xml to writing json data.
