Why is the Execution Min Time of every query always 0? Does it have an impact on the AVG time?
This is no bug of Statsviewer. There is a bug regarding the detection of the executionMinTime of QueryStatistics in Hibernate that has been documented in this JIRA ticket: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2948 However this value has no impact on the average execution time of a query. This computation is correct.
