      Description

      Yourkit analysis of the Portal bootup process has found a bottleneck in the ServletContextUtil.getLastModified() function.

      Performance improvement to this function is gained by a refactor from recursive to iterative. Thus, instead of doing depth-first search, we do a breadth-first search and do not have the overhead of recursive calls.
