>          URL:
>      Project: Geronimo
>         Type: Improvement

> The method getLastModifiedInDir in the hot-deploy/src/java/org/apache/geronimo/deployment/hot/
is using the algorithm by calculating highest modified time of any files or directories, this
could be improved.
> In fact, we only need to check every directory is enough, because any changes, for example,
add, remove, edit any files in a directory, the change can be reflected by its parent directory's
modification time, so  we don't need to check files.
> I also write a patch for the issue. A simple performance testing shows that the patch
will improve 58% of the performance.
