[Dovecot] Directory Layout Performance

[Mario Antonio Garcia]

 From a performance perspective:
Which Directory layout is better:
1. All mailboxes are stored in a single directory and prefixed with a dot
or
2. Maildirs using physical directories, such as: Maildir/folder/subfolder/

It looks like the second option -- File Sytem Layout (LAYOUT=fs) -- 
could spread the load in a better way ......
I do not expect a user  reaching maximum number of subfolders in linux , 
but what about those heavy users with a lot of sub-folders:
Is there a significant performance gain by choosing a specific  
Directory Layout ...

Any Comments?
