That's what I found regarding disabling SMB2:
On clients:
sc config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc config mrxsmb20 start= disabled

On the server:
HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters
Value name: Smb2
Value type: REG_DWORD
0 = disabled
1 = enabled

To enable it again on the client:
sc config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi
sc config mrxsmb20 start= auto

I restarted the computers to be on the safe side.

The result:
http://almosthappy.de/duhLd6Tm1GQoC3j0YyiJ637IS/capture.win7.smb1.first_client (15MB)
http://almosthappy.de/duhLd6Tm1GQoC3j0YyiJ637IS/capture.win7.smb1.second_client (15MB)
(Where "second_client" means: The same computer but another client already
had the application open.)

There was no noticeble delay. So it does not seem to be related to SMB2.

I was a bit lazy and installed the packages from Debian experimental
(2:3.5.0dfsg-1). Unfortunately the upgrade made some problems. It kind of
worked, but the application did not. I was glad when I successfully
reverted all the changes. But as the problem does not seem to be SMB2
related, I did not persue this any further.

If it was helpful I could try again with 3.5.0 from the git repository.
