PERF : Modify operation can be speeded up by a 10 times factor
--------------------------------------------------------------

                 Key: DIRSERVER-1468
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1468
             Project: Directory ApacheDS
          Issue Type: Improvement
            Reporter: Emmanuel Lecharny
             Fix For: 2.0.0-RC1


The Modify operation is quite costly, as we do up to 10 lookup. Each lookup leads to a ServerEntry
clone, a costly operation. If we measure all the time consumed in such clone operation, it
goes up to 84% of all the CPU time.

We can most certainly spare 8 or 9 lookups, speedup the operation by a factor 5 to 10.
