I still have bad smbfs write performance to both Samba and Win95 Servers.

>From Linux 2.2.7pre-3 client to Linux 2.2.6-ac1 Samba-2.0.3 server:
smbfs write speed: ~33KBytes/s
smbclient write speed: ~500KBytes/s
smbfs read speed: ~800-900KBytes/s
smbclient read speed: ~800-900KBytes/s

>From Linux 2.2.7pre-3 client to Win95a(with all patches MS) server:
smbfs write speed: ~28KBytes/s
smbclient write speed: ~9KBytes/s
smbfs read speed: ~550KBytes/s
smbclient read speed: ~600KBytes/s

Same results whether or not the Win95 bug fix was included in the kernel.
Same results whether or not smbfs is compiled into the kernel

These results look the same as 2.2.6.

I got the smbfs speeds by using time to see how long it took cp to complete. I
used a different file each time so caching souldn't affect results.
smbclient speeds came from smbclient itself.
