      Description

      We are currently running 2 separate Solr servers - refer to screenshots:

      • zasolrm02 is running on Solr 6.4.2
      • zasolrm03 is running on Solr 6.6.0

      Both servers have the same OS / JVM configuration and are using their own indexes. We round-robin load-balance through our Tomcats and notice that Since Solr 6.4.2 performance has dropped. We have two indices per server "searchsuggestions" and "tradesearch". There is a noticeable drop in performance since Solr 6.4.2.

      I am not sure if this is perhaps related to metric collation or other underlying changes. I am not sure if other high transaction users have noticed similar issues.

      1) zasolrm03 (6.6.0) is almost twice as slow on the tradesearch index:

      2) This is also visible in the searchsuggestion index:

      3) The Tradesearch index shows the biggest difference:
