Just to add some data, I tried that:

41113 directories, 492946 files, 48154 directory pages
total file size        130761550629 bytes (124703.93MB)
average file size      265265 bytes
total directory size   171589632 bytes (163.64MB)
average directory size 4173 bytes
estimated RVM usage based on object counts, 203980644 bytes (194.53MB)
estimated RVM usage based on 4% rule,       5237325610 bytes (4994.70MB)

But another question came up:

WARNING: '/bla' needs 373 pages and won't fit in Coda

- at first: Is there anything, I could do about that - or will anything be 
done about it?
- what happens, if I try to move /bla into coda?
