Subject [jira] Created: (JCR-2218) NodeEntryImpl.getWorkspaceId() very inefficient

NodeEntryImpl.getWorkspaceId() very inefficient 
------------------------------------------------

                 Key: JCR-2218
                 URL: https://issues.apache.org/jira/browse/JCR-2218
             Project: Jackrabbit Content Repository
          Issue Type: Improvement
          Components: jackrabbit-jcr2spi
            Reporter: Michael Dürig


NodeEntryImpl.getWorkspaceId() calculates its path on each call by calling itself recursively.
Further each call to getWorkspaceId() results in various calls to the path and item factories
which might be somewhat expensive by themselves. 

In my test scenario I have a RepositoryService.getItemInfos() call returning ~1000 items.
Processing these items results in about 2700000 (!) calls to getWorkspaceId(). Profiler data
shows, that 98% of the time to process the 1000 items is spent in getWorkspaceId()  and related
calls.
