--------------------------------+-------------------------------------------
 We have a repository with about 7000 resources. If a user opens, modifies
 and saves a feature source for an unmanaged connection for example it
 takes between 45 and 60 seconds to process the cache cleanup after the
 save takes place. While this is happening the CPU is pinned at almost
 100%.

 In this particular case there are practically no session resources, just
 data resources. The features being edited are related to layers associated
 with a map that is tiled, but there is no populated tile cache.

 If this happens with just one user, the system could become unresponsive
 if 2 or more Authors were working on resources at the same time.
