Thanks for answer, Miguel.
I use "socket options" because 99% places in Internet recommends this, and
no one say about "modern kernels" - really. You are first :) And of course,
this options not give me any visible effect.
I will try with "use sendfile = yes" but i`m not sure about this help..
Say me please, what transfer speed in the yours LAN ? Speed between Windows
clients and SAMBA server ? You have done some test? I ask this because i
can`t believe what SAMBA can do good transfer speed.
My test show me bad results -
Linux->Server FTP = 100 Mb/sec
Linux->Server NFS = 80-100 Mb/sec
Windows-to-Windows = 50-80 MB/Sec
Windows -> Server = 14-20 MB/sec. And this is my most pain :(
Linux -> Server (CIFS) = 10-20 MB/sec
Can you show me, how yours SAMBA work in Gigabit LAN ? What speeds ?
