Your server run very good. In the my end I recive only 30%.
I found hylafax quality checking to restrictive.
So I patch source.
1) training restricted to 9600 and below
2) If page recived fisrt write to disk then we wait confirmation message.
     So if anything is recived nothing is cleared.

With my patch I recive 0.5 pages  1.5 pages and so on.
Patch is against 4.1.2 . I lazy to upgrade.
