[jira] [Updated] (OAK-924) Optimize namespace lookups

     [ https://issues.apache.org/jira/browse/OAK-924?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alex Parvulescu updated OAK-924:
--------------------------------

    Attachment: OAK-924-bench.patch

attaching a first take on a benchmark test for the login-registerNS bits that happen in sling on each login call.

I'm not yet sure it's obvious where the slowness comes from, at least it should help get this issue going.

> 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.
