Increase performance of RPC and ZeroMQ in bitcoin-core

I am interested in the possibility of increasing performance of my Bitcoin Core RPC and ZeroMQ subsystems.

I know there is a setting for controlling the number of threads used by the RPC process, rpcthreads=x, but is there a similar setting for ZeroMQ?
