[Samba] Really bad Read performance

Hi Thomas,

Your is a common complaint on this list and typically it always seems to
come back to network hardware problems rather than software.

Run ifconfig on your interface and see if there are any errors listed.  If
you see none then i strongly recommend you swap the cable, NIC, switch/hub -
very good chance this will take you closer to a solution than fiddling with
Samba parameters which are best left on their defaults!

It has happened to me a couple of times.  When the network hardware is
working properly you see great performance from a default Samba install.

Good luck,

Subject: [Samba] Really bad Read performance

Running Samba 2.2.7, compiled with LDAP support. I'm suffering from really
poor read performance problems on the server. Write speed is fine (after
adding "interface = <ip of eth0>/24"), giving about 4.4 MB/s. However,
reading files from the samba shares is just not usable. Reading a large (34
MB) file from the server takes more than 3 minutes on a W2K Pro client.

NIC on both server and client is set to 100/FD.

I've tried changing "socket options = ...", but no settings I've come accoss
makes any difference.

Does anyone have any good ideas as to what I can do to fix this?

Regards, Thomas
