Jukka Zitting commented on OAK-1418:
------------------------------------
Good point about the statistics gathering. In revision 1574575 I optimized the
way the various access time stamps and counters are updated, which brings us on
par with Jackrabbit Classic:
{noformat}
Apache Jackrabbit Oak 0.19-SNAPSHOT
# ReadPropertyTest C min 10% 50% 90% max
N
Jackrabbit 1 3 4 4 4 36
15061
Oak-Tar 1 3 4 4 4 40
14749
{noformat}
The reduced perform() overhead also shows up in slightly increased percentages
of time spent in component calls:
* 42% in Tree.getProperty()
* 22% in RefreshStrategy.needsRefresh()
* 13% in getOakPathOrThrowNotFound()
> Read performance regression
