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.
