Saturation can partially be mitigated by doing the following, deeply
tested by myself:

1. By contracting an Internet Service which follows the International
Computer Science Institute quality standards, testable at
http://netalyzr.icsi.berkeley.edu. Many times bandwidth saturation is
caused by an improper upload buffering from the Internet Service
Provider, which will affect not only the Ubuntu One Client but any
service that uploads to the Internet.

2. If you are pretending to use a wireless network, only use routers
which are IEEE 802.11n compliant. This standard uses more advance
algorithms than its predecessors for assigning bandwidth to links.

3. If you are using a home router, disable any feature which doesn't
belong to any standard but are specific from the router's manufacturer.
These generally are the firewall and the Quality of Service features,
except Wireless Multimedia Extensions (WME or WMM). These specific
functions trend to dramatically increase network latency when the link
gets saturated.

4. If any application being used give an option to limit bandwidth,
limit it to the 80% of the contracted one. This will ensure constant
throughput for that program and faster initialisation for other services
while bandwidth is being negotiated between them.
