Just confirming you are talking about storage space, not link spped, like Lachlan's previous msg.
This is the type of characterization we would like to see documented - and perhaps reflected in a document...

In times of QoS this assumption may be very wrong. E.g. You have two
wires to the internet. One 1MB and one 100MB, but for the 100MB only
HTTP is allowed all other protocols have to use the 1MB link. If youre
first connection is an HTTP one, then the 1MB link will be overshot, the
other way round you'll have to wait for a long time to satisfy the 100MB
if you increase just linear.
The first mentioned problem, with 1MB link get 100 MB data could be
solved in one RTT, but in this case 99MB data get dropped. This would be
an overshot of the factor 100 and much worser than slowstart.
