So your biggest table is actually 229 MB. Something is not adding
up. I can't see any way to reconcile your previous statements with
this number. There also hasn't been any real explanation for the
statement that you have 250000 files. There must be something which
matters here which hasn't yet been mentioned. Any ideas?
