Hello I've a W2008 R1 serveur which have to send 750GB every day to a samba machine between a 1GB link. 1) What transfer rate should I have to wait ? 2) I've done the following in the Windows server in the registry /Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] "PagedPoolSize"=dword:ffffffff "PoolUsageMaximum"=dword:0000001e [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters] "TcpWindowSize"=dword:0000fc00 (faf0) "TcpTimedWaitDelay"=dword:0000001e [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters] "DefaultSendWindow"=dword:0000fc00/ and / netsh interface tcp set autotuningconfig=disable/ Between two windows server i can have 90Mbps but with a samba share i only have 9-11Mbps. What parameters must I give to my samba ? Thanks -- Herv?
