             Summary: [Proposal] Update KahaDB stats to be micro-seconds instead of milliseconds
                 Key: AMQ-8414
                 URL: https://issues.apache.org/jira/browse/AMQ-8414
             Project: ActiveMQ
          Issue Type: New Feature
            Reporter: Matt Pavlovich


Modern disks are fast, and measuring time in millis is not fine grained enough to get correct averages when there are a few blips in performance.

Current:
{noformat}
System.currentTimeMillis() - start
{noformat}

Proposed:
{noformat}
System.nanoTime() / 1000 - start
{noformat}
