Of course, but any message passing only adds a constant overhead to a single
message. Performance increase can also be achieved by adding new interfaces,
which remove the need to send several messages (by replacing them with a
single message). I think this is what is planned for fork. Faster computers
make the constant overhead for single messages negligible.

Also, AFAICS, there is no reason why any message interface generator should
be significantly slower or faster than any other.
