Michael Dürig commented on OAK-1757:
------------------------------------
bq. so the granularity of individual measurements is not that significant
I doubt this. This is a quantisation effect, which is inherently non linear.
> 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%.
