There is a bug report concerning this up:

Bug 338402 - File system cache is inneficient : too many file per directory

You may want to cc and comment on it, as I did now too.

I also reported:

Bug 332013 - NFS with NetApp FAS: please split payload files in file_db_data 
into several directories to avoid reaching maxdirsize limit on Ontap / WAFL 
filesystem 



And then we have:

Bug 341884 - dozens of duplicate mails in ~/.local/share/akonadi/file_db_data 


If you didn´t akonadictl fsck it yet, can you try running

ms at merkaba:~/.local/share/akonadi/file_db_data> fdupes -m . 1736 duplicate files 
(in 1729 sets), occupying 8.6 megabytes

and check what you get? It may take a huge time. I did this run after an 
akonadictl fsck, so it may have removed most duplicates.

Ciao,
