Unhappy File transfer speed to slow!!-HElP!!


HI

I have a strage problem whit one server, i try to describe the problem but if u need more information just let me know and i tell u.

So we have a server and we have instales an Open suse 10.3 on it.
We created a Samba server also.
Made to share folder, that we acces from network from other computers that have xp.

The problem is if we try to copy from server it is very slow only 100-300kb/s.
The strange thing is that if i copy 1 file then its slow but if i start to copy another one the speed gos up to 10-15mb/s. Evry time i want to copy somethin or install from that server i need to start another copy.
If i copy from a comp to that server the speed is normal only if i copy from server its slow.

PLz help
Thx

Networking issue?

I had a similar problem when the client computer was M$ Windows, and found it was a networking issue. At least this is where I would start looking.

Might want to install Wireshark and see if you are getting a lot of retransmit requests from one of your systems.

Well basically the samba box is sending packets that are too large causing the Windows nic to overflow the Receive Buffer.

The solution is to adjust the packet size samba sends, even though the problem lies with Windows XP.

Here is a link that explains the problem and solution in detail.

Hope this is helpful
