I am in the process of compacting my DB (it has been running for at least 2.5 hrs. already) and I noticed some peculiar results:
group size (assume Original) size (assume after compacting)
a.b.dvd 6.77 gb 18.23 gb
a.b.hdtv 8.7 gb 11.78 gb
a.b.hdtv.x264 11.16 gb 19.89 gb
a.b.multimedia 4.6 gb 13.67 gb
a.b.comp 1.6 gb 12.38 gb
Other groups have the reverse (expected) size change - but not nearly as dramatic.
Does this make sense?
