man fileserver says:
The maximum number of directory entries is 64,000 if all of the entries
have names that are 15 octets or less in length. A name that is 15
octets long requires the use of only one block in the directory.
Additional sequential blocks are required to store entries with names
that are longer than 15 octets. Each additional block provides an
additional length of 32 octets for the name of the entry. Note that if
file names use an encoding like UTF-8, a single character may be
encoded into multiple octets.
It also goes on to say:
In real world use, the maximum number of objects in an AFS directory is
usually between 16,000 and 25,000, depending on the average name
length.
But that really depends on your "real world" - we have a number of directories
here that have 60,000 or so objects in them. In fact, to hit a limit as low as
16,000 entires, every filename would need to take up 4 slots, which means every
name would have to be more than 80 characters long.
