Running samba with Ubuntu, default configuration, one share, samba running as daemons rather from inetd. Copying one file between the share and another machine on the LAN is very slow. Adding another copy and both transfers proceed very quickly. The client machines are Macs with recent OSX, and a Windows laptop. Same behavior. If the second transfer is initiated on a different client, both transfers still speed up, dramatically. Any ideas? Thanks in advance.
I run Samba on Ubuntu in an Active Directory environment and don't (any longer) see strange slowness. Can you sanitize and post your smb.conf for starters?

Problem went away when we removed an ethernet switch box from the network. Thanks much, you and other responders. ~~~David~~~
