Hi I'm testing my Solr instance with multiple simultaneous requests. Here's my test.
For an index of ~200K docs, I query Solr with 10 simultaneous threads. Can someone help me explain/improve the following observations: 1) Solr doesn't seem to use all the available CPU to improve response times (query times are good, but the time required to return documents aren't so good). My CPU seems to be running at ~30% 2) As expected, time for response increases as the num of requested results increase. What's surprising (and perplexing) is that Solr seems to use *more* of the CPU when I'm requesting *fewer* docs. Consequently, its performance in returning a larger result set is very bad 3) To counter 1, is there a way to make two Solr instances search on the same index (so that concurrent requests are served faster) Any help in this regard would be very useful.
