...s transfering with a reasonable speed and after having transfered around 16 megs it slows down. I tried many configuration options regarding locking, tcp settings, xmit size and every combination that could make any sense for me. Then I gave up with this configuration mess as I could lower the performnce easily, but the performance jittering was the same. Now a few notes before I continue: I tested the FreeBSD server on the loopback interface and the file write speed was around 43 Megs that is close to the disks maximum. I also tested the XP machine with a Windows server and the write performn...

...ting from earlier addressing this, but I can't get the right combo of key-words to google up the solution. If I open a file (say a .doc) from windows explorer, the program launches and that file loads quickly. If I use the open dialogue from the application, the file loads slowly. Looking in performnce monitor I see that if I load the file from explorer, there is a quick exchange of received bytes from the samba server, and nearly none sent. If I open from the open dialogue, I see an almost equal amount of sent and received bytes. I've seen this behaviour before in all circumstances if I...
