Which flash server i should use for flash chat with a lot of instant users?

Question

I'm currently developing flash chat for social networking websites like facebook. Actually i want to develope flash chat in this game. Chat would have a lot of instant active users. So that, i need to know which flash servers i should use, is there any free ones that are pretty good for such high performance needs?

I've found ElectroServer4 Professional. Is it enough for my task?

Thank you

Answer 1

One free one is Red5 (http://code.google.com/p/red5/) I haven't messed with it in a while but it seemed pretty decent.

Answer 2

I asked a similar question a while ago: Best Flash Audio/Video + Interactivity server?

I ended up going with Wowza Media Server, and have no complaints so far. I had bad luck with Red5, I would not recommend it.
