I actually work on the server side, specifically the web interface, and
know embarrassingly little about the desktop client.
I do know at a fairly high level, though, that the desktop client
maintains a connection to the Ubuntu One servers and monitors
synchronised directories for changes.
Those changes are then synchronised on the server (hence they appear
instantaneously in the web interface) and a signal is sent to all
connected clients, causing them to download the updated files. You can
see all this in your syncdaemon log in $HOME/.cache/ubuntuone/log or in
the syncdaemon source code, if you're so inclined.
There are lots of reasons why the updates might not be happening as
quickly as expected, including network flakiness, network traffic or
system load at either end or in between, server updates, service outages....
As a test, I created a file on my Natty desktop in a folder I have
shared with my wife and it appeared on her desktop within a few minutes
of resuming from suspend.
