What kind of numbers are you thinking about (per shard online at the same time?) – Roy T. Feb 12 '11 at 15:00
"Thread-per-connection" and "massively multiplayer" don't go together. – Kylotan Feb 12 '11 at 17:18
so what do you mean its not going to go together ? i guess the numbers are as high as can i go with min cpu+ram – user3689 Feb 12 '11 at 17:33
Threads don't scale well beyond a few hundred connections. If you want to hit server concurrency >500, you need single-process async networking models more like libevent. – coderanger Feb 12 '11 at 19:33

If you are thinking about a real time MMO and not a social MMO, it would definitely be worth taking a look at MV3D which is open source. It is mainly geared towards having a less lightweight client than flash, but I'm currently using it to make a browser based game and it's going well.

For a social MMO, I'd suggest building the server on the web framework of your choice rather than making your own server application. You can architect and scale your server similar to how large websites do it. There are plenty of online resources for doing that.

For either way, a great place to look is In particular, here's some info on Playfish's architecture.
