“microsecond performance” irks me because you can’t get latencies of a microsecond without very expensive special network cards and APIs which they don’t seem to mention and I doubt they use. So they either mean 10s to hundreds of microseconds or they’re taking the reciprocal of their throughput which would be weird and misleading.

If you’ve made a fast product that’s great! Show us with well-explained benchmarks not the term which sounds best but you can still hand wave as justified, because it’ll make people suspicious.
