mount.cifs is slow.

I can successfully mount a remote resource of a windows PC,
but somehow the transfer rate is too slow to even play a rmvb movie.

It can't be the drivers problem cause I can get over 1 MB/s with my ppp0 adapter.

Here's the command I used:

Code:

mount.cifs //12.34.56.78/resource /mountpoint -o user=xxx,pass=yyy,iocharset=utf8

And adding "directio" or "rsize=32768" into options doesn't help at all.

I already found a discussion titled "Slow transfer with mount.cifs", but it didn't provide any effective solutions for me.

Is your distribution up to date with regard to samba?

Transfer Speeds

I found that I got a MUCH better transfer speed when I had the following settings in /etc/samba/smb.conf
[global]
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=65535 SO_RCVBUF=65535
There is something similar in the example file above, but its easily missed.

ehawk:
Thank you very much, my problem is fixed !

After using iperf to probe my network speed, I found that it has lock on a rate of 10 MBit/s.
Then I started to suspect if there were the problem of the network interface, and found a parameter in the remote firewall which didn't setup well.

Now my network can run up to 90 Mbit/s.

Though this is a stupid mistake, but still thank you so much.
