Can you give some information about this bug please? Maybe it gives me a
hint for my similar problem here: When I copy from a W2000 PC to the
Samba server using the W2K explorer, I get very good performance in the
same range as copying to a NT server, but when I use Windows Commander
instead, the speed goes down to about 1/10. The same copy to a NT server
runs with full speed.

I found this problem with 2.2.1, but upgrading to 2.2.2 did not help.

Most strangely: If I start ethereal or tcpdump on the samba server to
watch the net traffic, the copy speed with win commander goes up to full
