I occasionally wonder how much of the polled network/storage performance gains being talked about are in reality mainly about the effect of CPU idling.

If I instead make the server busy-poll for network activity (by just loopping around non-blocking recv), while waiting for the next query, I get even better numbers than shown there. Even though it's still interrupt based network processing.
