Solr Qtime difference to real time <p>i am trying to find out what causes the difference between the Qtime and the actual response time in my Solr application. The SolrServer is running on the same maschine as the program generating the queries. I am getting Qtimes in average around 19ms but it takes 30ms to actually get my response. This may sound like it is not much, but i am using Solr for some obscure stuff where every millisecond counts.</p> <p>I figured that the time difference is not caused by Disk I/O since using RAMDirectoryFactory did not speed up anything.</p> <p>Using a SolrEmbeddedServer instead of a SolrHttpServer did not cause a speedup aswell (so it is not Jetty what causes the difference?)</p> <p>Is the data transfer between the query-program and the Solr-instance causing the time difference? And even more important, how can i minimize this time?</p> <p>regards</p>
