Hey samba-people,

just our anecdotal findings and advice:

Directory listings from our MacOS clients took a big hit when we 
switched from AFP shares and SMB shares from our old Mac OS Server to 
the new debian fileserver with samba shares.

Especially opening big directories with AFP is blazingly fast, while in 
samba it takes forever. E. g. we have a directory with 37k 
subdirectories and 245k files in one level. Opening this dir on a Mac 
via a samba share take approx. 9 minutes. Our advice was to reduce the 
amount of files in a single directory and create cronjobs that 
automatically moves files into subdirectories.

Any improvement on samba server would be greatly appreciated!

Thanks, Matthias Kühne.
