Depending on how long running these processes are you may be able to separate them out completely into separate server processes in true client server mode. Effectively creating a network process for each network then have a load balances so that each incoming request gets sent to one of the server processes. That way you can scale linearly by adding moreservers as required (the load balancer starting a new process each time the number of active requests passes a given limit.) This is how many uindustrial scale databases handle high processing loads, each SQL request is validated and if OK passed to a query server, the queries are distributed over the available servers to ensure even loading and each server can run on separate CPUs as needed (but still controlled by the OS). The downside of this is of course the complexity of writing the loadbalancer which must track all incoming requests and which server they are on and also handle the responses from the servers when complete, making sure they go back to the right source. Its a little bit like writing a web server... or at least the listener part.
