I very much doubt that the OP's problem is what he thinks it is,
i.e. that copying over a local TCP connection is what makes his
application slow.

No, it doesn't. Instead, it is the operating system itself which
distributes the requests: the parent process opens the server socket,
then forks the actual server processes. They all do accept, and
the operating system selects an arbitrary one for the next request.
That process returns from accept, so for the next incoming
connection, one of the remaining processes will be selected.
