Hello,
How much latency is "a good latency"? Is it within the spec's allowed range?
It seems quite natural to me that different devices return their answer after different amounts of time. After all, you're requesting the device to fetch some information for you. A root complex (usually the CPU or its memory chip) merely gets it from its DDR memories. An NVMe needs to grab it from a flash memory. Which takes a bit longer, I guess.
So as long as the latencies are within spec, there's nothing to be alarmed about.
Regards,
Eli
