on my production system, I've scanned 97559 dirs in total, including 'tmp's, Maildir & homedirs. Control and Indexes are located elsewhere.
There a total of 97406, 5238 of them use more than one block, hence, 92168 are skipped from the stats below.
Then I compared the size of the directory file with this:
filename size = sum of length of all entries in the directory
- 10 * number of entries in the directory
The ratio is calculated: size of directory file divided by filename size
ratio num of dirs <2 1593 3 810 4 228 5 129 6 122 7 65 8 56 9 31 10 30 11 27 12 21 13 18
Top ranks are: fnamsiz dirsiz ratio 23 1417216 61618.09 23 1089536 47371.13 23 872448 37932.52 23 839680 36507.83 23 802816 34905.04 23 684032 29740.52 23 684032 29740.52 23 655360 28493.91 70 1847296 26389.94 23 593920 25822.61 23 581632 25288.35 23 536576 23329.39 23 532480 23151.3 23 516096 22438.96 23 503808 21904.7 23 471040 20480 23 446464 19411.48 23 425984 18521.04 287 5005312 17440.11 23 376832 16384
There are 2175 dirs with a ratio >= 10.
There are 1613 directories with a ratio >= 100, 747 "/cur" 492 "/new" 372 "/tmp" 1 Maildir itself 1 .dovecot.rawlog
Nearly all of them are: INBOX, Trash & SPAM folders. The two last ones with various names depending of the IMAP client used.
