Check the number of extents, particularly if it's a Dictionary Managed Tablespace. Last week I had to drop a user who'd managed to have close to 50,000 extents, a single segment had over 20,000. It took Oracle a few hours to do the processing for that. Converting that instance (fortunately just a prototyping instance) to LMT with uniform extents is on my to-do list :-).
