Hi, It is also likely that your indexing is using resources and that there are not enough resources for queries to process. Indexing can put stress on heap and GCs might be slowing Solr down resulting in observed latency. Can you tell us a bit more on size of your index, server configs, heap size, indexing rate, how do you do indexing (batch size) and query rate. This might give us better ideas to point you into right direction. Do you use anything to monitor your Solr/host? Does monitoring tool suggest that there are some bottleneck?
