             Summary: Oak eats too many CPU cycles when idle
                 Key: OAK-1757
                 URL: https://issues.apache.org/jira/browse/OAK-1757
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: jcr
            Reporter: Michael Dürig


An idle Oak eats roughly 5% of my CPU cycles. 

This is caused by the {{Clock}} implementations introduced at 
http://svn.apache.org/viewvc?view=revision&revision=1575050. Scheduling the 
fast clock to update its time every millisecond is quite expensive. 
Substituting for the simple clock reduces idle CPU usage to below 1%.
