             Summary: Optimise path parsing
                 Key: OAK-1015
                 URL: https://issues.apache.org/jira/browse/OAK-1015
             Project: Jackrabbit Oak
          Issue Type: Sub-task
          Components: core
            Reporter: Michael Dürig


As Jukka [mentioned | https://issues.apache.org/jira/browse/OAK-978?focusedCommentId=13751242&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13751242] on OAK-978, is often on the critical path and the changes done there had a bad impact on performance:

{code}
Apache Jackrabbit Oak
# ReadPropertyTest               min     10%     50%     90%     max       N
Jackrabbit                         4       5       5       6      14   11287
Oak-Tar                           14      15      16      16      27    3855
{code}

Until we are able to come up with a better solution that separates parsing from name mapping, I suggest to use the following heuristic to shortcut path parsing: shortcut iff the JCR path does not start with a dot, does not contain any of {}[]/ and if it contains a colon the session does not have local re-mappings.
