Alex Parvulescu commented on OAK-924:
-------------------------------------
I've pushed the patch in with some changes, thanks Jukka for the (offline)
feedback!
It doesn't look much better, but it's still some work to be done.
I see 2 issues
- acl eval makes the property reads slow (this is why the perf is not there
yet)
- the #init keeps a cache of the initial mapping as maps. Unfortunately
removing the maps makes the code almost 3.5 times slower.
> Optimize namespace lookups

> 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.
