Sorry, by dl I mean downloading large file from server to remote desktop -
The server is uploading to desktop.
I want the children to use all the available bandwidth within the
'extranet' queue - The child 'poshta' queue NEVER goes above using 34%,
even though all other queues have no services running on them and 'poshta'
is set to borrow.  If I leave 'poshta' queue at 34% and set all others to
1%, the 'poshta' queue is still never pushing out more than 34% / 37KB.

If I set it to '90%' it pushes out at ~90KB - wondering why it's not
borrowing when parent has unused bandwidth.
