[ https://issues.apache.org/jira/browse/OAK-2707?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Joel Richard updated OAK-2707: -- Attachment: OAK-2707.patch [~anchela], in Sling the namespaces are read when you read the first property of a resource which contains a colon. Thanks to some other changes, we could reduce the overhead already to around 5% of the rendering time, but it would be great if we could remove it entirely. I have attached a patch with a namespace cache. Can you please review it? It still contains a few todos with things I wasn't sure about.
