Keith Turner created ACCUMULO-4779:
--------------------------------------

             Summary: Instantiating iterator access config in a very slow way
                 Key: ACCUMULO-4779
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4779
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.8.1, 1.7.3
            Reporter: Keith Turner


I noticed this will looking at profiling data.  When creating iterators all configuration is put in a TreeMap just to get two keys out.

The following code 

https://github.com/apache/accumulo/blob/rel/1.8.1/start/src/main/java/org/apache/accumulo/start/classloader/vfs/ContextManager.java#L118

calls the following code
