It is lower than my usual solution which is to pipeline requests to another process over a pipe. That solution has an overhead of about 1us per call.
As for not blocking, the OTP team is working on getting dirty schedulers to be a first class system. The overhead there is also pretty low, but now you don't have to worry about blocking the schedulers anymore.
What is pricey in a NIF is conversion of data back and forth more than the overhead of the call itself. it is usually quite fast.
