Each WebSocket class instance runs in a different thread (in release mode). If you define variables in the Page class, then they are not shared among users. Variables in a module (like ABMShared) are.

There isn't a straight answer to that. At some point your will probably have to look into load balancing, using multiple physical servers etc.

Some articles that can give you indications:
