Alex Parvulescu commented on OAK-924:
-------------------------------------
Had a quick chat with Jukka about the state of this issue.
Things I'd like to tackle next are:
- add a commit hook that builds a reverse URI->prefix mapping, this should
optimize the access patterns
(this could also keep a list of all registered URIs and prefixes to optimize
the #getPrefixes() and #getURIs() calls)
- remove the SessionNamespaces#init call
- move the default ns (static) map to the initial content
> 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.
