Alex Parvulescu commented on OAK-924:
-------------------------------------
In rev http://svn.apache.org/r1530299 I added another ns related benchmark
(NamespaceRegistryTest).
It seems that there is quite a difference between JR and Oak on this one (90%)
JR is at 4ms while Oak is at 400ms.

> The current namespace handling code does a lot of repetitive work, which
> shows up in hotspots like XML imports and Sling's namespace mapping code.
