Hi,

I don't know who can tell me.

I have three machines.

Two of Windows Server 2003

One is Samba 3

All network is connect 1G NICs.

And Switch are all Gigabyte.

When I transfer Windows to Windows.

The Speed have more then 500Mbits.

But when I transfer Windows to Samba

The speed only 150Mbits.

And sometime will low spped to 70~80Mbits.

Is it Samba limited?

Or how to fix it?

Thanks a lot.

It shouldn't.

You probably would need to check 'socket options'.

We have a similar problem sometimes. What should be the ideal value for
'socket options' in Samba v3.x?

Thanks

The recent discussions on this list had showed that with
recent kernels there is no need to use SO_SNDBUF and SO_RCV_BUF.

Remove it completely. Sockey options should not be needed with Linux kernels
2.4 or layter. Check out your networking hardware - NICs, HUBs, Switches and
cables - the quality of these have a significant impact on network
performance. Also, use 'ethtool' to verify that your NICs are operating at
the maximum speed.
