Ah, ok so you are considering the latency rather than the throughput. I was thinking that being able to perform the update within 16.6ms should not be too hard - there is a sibling comment about SSD latency but the working set should fit in RAM.

Sure, so there will be latency, maybe 4-5 frames with input lag. But this is normally bearable in a game so I'm guessing that it would work fine for an office app. It would be difficult to remove, but 80ms response time from an application that can always hit its 16.6ms deadline should be workable.
