Hi, I want to use twisted to write a server which is to get purchase orders from about tens of thousands clients sent by wireless net work (tcp protocol) and store the orders into a DBMS system. I wonder if it is possible and how to deal with the high concurrency.

It is possible. Dealing with concurrency depends on how many clients will be connected at a given time, and how many requests you'll need to process in parallel. If all of them, you'll probably want Linux with epoll reactor, and it may be you'll need a distributed architecture with multiple servers.
