Slap a trace on and see how frequently you're getting uet/fet operations and you might get an
idea.
For future such operations, a common technique is (iirc) along the lines of:
- truncate reuse storage
loop
- alter table X deallocate unused keep nnn
end loop
so you can free the extents in a more incremental and controlled fashion
