Not difficult at all. We have a solution that fits both use cases by
default: it's the same solution we used with 1.1.0 and are now using
with 1.2 beta1, which is setting DeferUpdate to 1 ms. You and Pierre
have not provided any test cases which demonstrate that 10 ms is
beneficial, and Pierre admitted that the choice of that value was more
of a gut instinct, which is why we changed it back until further
information can be gathered. Pierre and I have reached at least a
temporary agreement regarding this, so I'm not sure what you hope to
gain by continuing to argue the point.
I'm pretty sure the message from Pierre was that it's not important enough
to block a new release; not that "we have a solution that fits both use
cases optimally".
We might solve the -DeferUpdate problem, but as long as the
VirtualGL/TurboVNC standpoint is "no compromise at all", "any CPU increase
is a no-no" etc, there will be tons of issues on which we cannot find
solutions that are optimal for both cases. Without room for compromises
and tradeoffs, it's an impossible goal.
Having a special script for the ultimate-performance-on-LAN-case would
be an easy solution.
