As another side note, command coalescing is worth experimenting with.
Might be, but I'm a bit skeptical. We might lose more to added latency.
Yes, that's the biggest item of note.
Still, it would be worth turning on if interrupts exceed a certain
threshold, such as 1000/second. Each interrupt handler setup and call,
even with PCI MSI, has a certain fixed amount overhead. Command
coalescing can mitigate that overhead.
