Thomas Mueller reopened JCR-2327:
---------------------------------
Assignee: Thomas Mueller
Creating a NodeId from a String is still a bottleneck. It's relatively easy to
improve performance (avoiding creating temporary objects, use switch/case).
There are some other issues: some errors are not detected, and the exception
should include context information.
> java.util.UUID.fromString() too slow
> ------------------------------------

> Key: JCR-2327
> URL: https://issues.apache.org/jira/browse/JCR-2327
> Project: Jackrabbit Content Repository
> Issue Type: Improvement
> Components: jackrabbit-core
> Reporter: Marcel Reutegger
> Assignee: Thomas Mueller
> Fix For: 2.0-beta4
>
>
> 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?
