samba - Jul 2016 - questions regarding 40G Samba Server

Hi,

forgot that... CIFS and NFS. May be we split both to different servers.
One CIFS, one NFS.

    Regards . Götz

CIFS is single threaded, if you plan on using it with a large amount of
users, you'll want to have faster cores. NFS is multi threaded, so you can
take advantage of additional cores better. Depending on how many users you
are serving, it sounds like a six core E5 (higher per core clock) would fit
well.

Thanks! single- vs. multi threaded is a good hint.

Oh, "my" cifs as a protocol is multi-threaded. It's part of the
Samba
implementation that is single threaded. However, for large file I/O
Samba is multi-threaded.
