[Samba] samba/network performance

Hi list,

we're having some problems with our Samba Server based on Debian Eth with Samba version 3.0.24. When a user copies a file to a share the performance is just about 10-15 MBits/s. Doesn't matter what OS the client uses. The server itself has a 1 G connection. Both are directly connected to the switch so there couldn't be a buggy cable/box between them. When i measure the speed with any other program, e.g. netio, it goes up to full bandwidth so there is no problem with the OS network configuration. I guess it's a problem in my configuration, but i can't find it.

Thanks for help and best regards.
