I have a computer at home with an Ubuntu Server 14.04. This server has several hard disks that are shared using Samba.

I have an iMac with OS X El Capitan 10.11.5 and I use one of the shared disks to store some information. I'm accessing this disk a lot of times to write and read information.

The performance of the Finder is really slow compared with my Ubuntu laptop and my girlfriend window's laptop...

The configuration for the disk on Samba is this:

    comment = my coment...
    path = /path/to/disk
    browsable = yes
    guest ok = yes
    read only = no
    create mask = 0755

I would like to know if the configuration of the disk should be different in any way, or maybe if I need to add some configuration in my Mac.

I also noticed that sometimes when I try to rename a folder inside this Samba share my Mac usually ask for my root password to modify the folder's name.


You should avoid using SMB on OS X (IMHO) as it has been buggy since the days of Snow Leopard (10.6), for me at least.

A quick Google search limited to this year alone brings up a myriad of issues regarding OS X and slow SMB implementations.

There are a few things you can try:

Personally, if I have found CIFS good, AFP better, and NFS (even though it's much older) to be the best in terms of performance.

  • Thanks ! I solved my problem with cifs://MYSERVERNAME. And the finder works pretty much better with this – AlvaroAV May 25 '16 at 13:43
  • Glad I could help....I was in the same spot you were in...for weeks ...thinking it was me messing up my configuration somehow. – Allan May 25 '16 at 13:45

Enable AFP (Netatalk) on your Ubuntu server and connect to the mount points using afp://

And get a lot of ._*,.DS_Store,.TemporaryItems,.apdisk,.Appledouble ones in each folder)))
