I have a relevant question about API throughput.  I'm using Diablo release
version and I found out that there's only one process of nova-api to handle
all API requests from even different users.  That results very low (<10)
API throughput (definition: API requests handled per second).  Similar
symptom was observed back in Cactus release.

Is there anyway to configure API service to run in multi-threaded mode so
that it can utilize multi-core hardware?  I'd really appreciate if anyone
can also shed some light on why Nova API was designed to work in this way.
 Thank you in advance.
