the tar  and gzip are mostly  BUILDING the cache.

Mock currently makes a cached copy of the buildroot it just created so it 
doesn't have to redepsolve and download/install the rpms each time.

So the first time you run it makes a cache. You aren't clearing out the 
cache each time, are you? That would definitely eat up a lot of time.
