I've worked in web tech long enough to recognize that the overhead of HTTP does not explain the difference in performance between "raw binary" protocols and ones that have textual headers.

Put another way I've seen extremely low-latency https servers. The latency in S3 doesn't come from using https.

Raw binary. As in I send the CPU instructions to seek to a memory location (whether local or remote). iSCSCI is usually on the same network (maybe even the same machine if using k8s to do this via Longhorn) and handled in kernel space.

I highly doubt HTTP has less latency than that.

no, but since that part of the data transfer wasn't the bottleneck, it doesn't matter.
