-

i ask more appropriate choose when developing server similar smartfoxserver. intend develop similar yet different server. in benchmarks made ones developed above server had 10000 concurrent clients. made bit of research regarding cost of using many threads(>500) cannot decide way go. once made server in java small application , had nothing heavy loads.
