[p2p-hackers] Testing scalability on a P2P network

[Greg Bildson]

Run it in the wild with a few million users and see if network performance
degrades.  ;-)  Seriously, sometimes that is what you have to do.

Obviously, some beta testing can help but it is not true that certain
features can scale indefinitely.  You need to make your app have limits that
it won't go beyond.  For example, you can't hold 1 million alternate
locations in memory for a file in a file sharing network.  You certainly
can't ping them all via UDP.  Being able to remotely turn off some features
or settings (again with boundary limits) can be useful.

There are some fancy simulators around for basic testing.

Thanks
