title: How can I bench mark query performance in postgreSQL? CPU or TIME but need to be consistant for every run
body: <p>How can I bench mark SQL performance in postgreSQL?  I tried using Explain Analyze but that gives varied Execution time every time when I repeat same query.</p>
  
  <p>I am applying some tuning techniques on my query and trying to see whether my tuning technique is improving the query performace. The Explain analyze has varying execution times that I cant bechmark and compare . The tuning has imapact in MilliSeconds so I am looking for bechmarch that can give fixed values to compare against. </p>
