Get say a few hundred or thousand simultaneous players (or bot's), and
this alone will drag almost any current OS model to the floor, Linux
encluded. FWLIW I use an asynchronous thread pool (again) to handle
network IO.

I use (I think) a base set of 5 threads for the DB. Essentially they
are service bnased threads, each thread supplying a basic service
within teh DB, or to outside callers. Typically each thread controls
an in-DB data structure which is private to that thread. After that
everything is just simple message passing between threads (I don't do
much call processing in the server, even in the internal language
implementation its all message based).

Some HTTP servers have built-in throttles for the number of
simultaneous connections they will accept from a given IP address.
