<span class="Apple-style-span" style>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. <div>
<br></div><div>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.</div>
