Research direction
Reproduce the issue with the C++ async_multi_get test on a 10Gb NIC, using 1,000–5,000 empty-data requests against Pegasus v1.12. Compare the server-side latency with the end-to-end time until callback handling completes; done means identifying the source of the extra 5ms or more and documenting a reproducible result.
