Xpra: Ticket #418: more aggressive speed tuning when bandwidth is available

If we have network bandwidth to spare, then we should push the speed auto tuning higher to make use of it, giving us a higher fps when we can sustain it.

Testing using a video player on a LAN, I got the best results using "--speed=100" (x264 "ultrafast") which consumed a lot of bandwidth at 1080p (peaks at 70Mbps) but when the bandwidth is available we should make use of it. (unless we decide to honour bandwidth constraints, see #417)

Too late in the release cycle to make this sort of somewhat risky change - re-scheduling.

Mon, 20 Jan 2014 11:13:43 GMT - Antoine Martin:

Some minimal changes were made in 0.11 to ensure we adjust the speed a little bit better, see r5206

Tue, 04 Feb 2014 16:37:36 GMT - Antoine Martin: status changed; resolution set

A number of changes have been made to try to keep the encoder more busy, notably: r5339 + r5340, r5299, this will do for now. (see also #502 and the receive buffer size changes)
