Comment (by Vort):

 > I guess connection via WANem is almost like connection via real WAN with
 loss and jitters, every moment is unique.

 You can't get 3209 KiB/s on 10 Mbit/s link.
 So WANem is not perfect (or, maybe, I've made some configuration mistakes
 somewhere).

 > and seems like it never shrinks in Windows7

 Looks like so.
 But if WANem produces bandwidth spikes, this also can be the reason for
 absence of shrinking.

 By the way, I wasn't able to make IDEAL_SEND_BACKLOG grow beyond 4194304,
 even on 100 Mbit/s link.
