The numbers I have seen are CXL latency around 250 ns while NVMe latency is 5-10 us (Intel Octane DC series for local flash).

You mention amortization for NVMe, but when operating at high queue depths the per-request latency is larger than at low queue depths.

Fast local NVMe drives aren't an alternative to disaggregated memory. There is no fabric with local NVMe drives. It would be necessary to compare against NVMe over Fabrics, which is quite a bit slower (look at flash SAN appliance datasheets, probably around 100 us latency).

Both the comparison itself and the numbers you mentioned are not what I expected. Can you elaborate and share links to numbers?
