[jira] Updated: (JCR-2327) java.util.UUID.fromString() too slow

["Jukka Zitting (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/JCR-2327?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jukka Zitting updated JCR-2327:
-------------------------------

    Component/s:     (was: jackrabbit-jcr-commons)

... In any case I think this should be treated as an internal performance optimization and handled entirely within jackrabbit-core, so I dropped jackrabbit-jcr-commons from the list of affected components.

> Benchmarking shows that the java.util.UUID.fromString() method is 10 times slower than the previous version we used from jackrabbit-jcr-commons. This method is quite heavily used in the query section or more generally whenever a NodeId is created from a String.
> I'd like to introduce the custom String UUID parsing code again that we had in the jackrabbit-jcr-commons UUID class and use it in the NodeId(String) constructor.
> WDYT?
