[jira] Created: (JCR-1988) AbstractRecord does inefficient List.indexOf()

AbstractRecord does inefficient List.indexOf()
----------------------------------------------

                 Key: JCR-1988
                 URL: https://issues.apache.org/jira/browse/JCR-1988
             Project: Jackrabbit Content Repository
          Issue Type: Improvement
          Components: jackrabbit-core
            Reporter: Marcel Reutegger
            Priority: Minor


AbstractRecord keeps a list of already used UUIDs and references
them by index when used again in a record. Using a List does not
scale well, when the record grows larger. e.g. a transaction of
10k nodes takes more than a minute on my machine when the journal
is enabled. Most of the time is spent doing List.indexOf() in
AbstractRecord.getOrCreateIndex().
