[Samba] Samba access slow

[Jonathan Courtois]

Hi everyone,

I configured a Samba serveur for a company, but it is quite slow to access
reading or writting files/directory and this slow the productivity of
everyone in the company. I might have missconfigure something, I will be
happy to have any advices.

I'm on a Debian Wheezy, Samba is installed on a LXC container also on
DEbian Wheezy. There is absolutly no Internet problem or speed issue, with
other services I have hightspeed service.

Some of my user access it via smb://ADDRESS (Mac) and other via Windows
\\ADDRESS

Here is smb.conf :

[global]
workgroup = WORKGROUP

netbios name = infrastructure
log level = 2

Also on the "access.log" file I have numerouos line for each file access,
and even sometimes multiples lines for the same file. They look like this :

[2015/02/18 14:57:47.342247, 2] smbd/close.c:696(close_normal_file)
xxxx closed file Bybat HAR/._Planning projet Bybat HAR.xlsx (numopen=3)
NT_S$
 [2015/02/18 14:57:47.423204, 2] smbd/open.c:746(open_file)
xxxx opened file Bybat HAR/._Planning projet Bybat HAR.xlsx read=Yes
write=N$
 [2015/02/18 14:57:47.551210, 2] smbd/close.c:696(close_normal_file)

Thank you very much for your help, deeply appreciated.
