Hi Anders
Finally I found the time for a benchmark, and it turns out that a complete
clone of 'data', using a 1.5Mb/s link, takes more than 3 hours.
I think that if we switch to git, and if we expect the size of 'data' to
keep growing at a brisk pace (addition of great new aircrafts, fancy new
models, ...), maybe we should plan to factor out parts of it into separate
repos.
If we move Aircraft into a separate repository (hosted on
hangar.flightgear.org :-) then we could push it to a widely-available SVN
hosting service (code.google.com) and stream to users on demand.
Think about it as the model for scenery & terrasync, but for airplanes.
I'll post another message with this idea, so that we don't clutter this
discussion, but I wanted to mention it here because it's related to how we
structure the repositories.
