As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks.

A co-worker introduced me to Craig Hanson and Pat Crain's performance mantras, which neatly summarize much of what we do in performance analysis and tuning. I've refuted many benchmarks by showing that they would require a network throughput that would far exceed the maximum network bandwidth (off by, for example, as much as 10x!).

Making queries to an inference engine has many of the same throughput, latency, and cost considerations as making queries to a datastore, and more and more applications are coming to depend on such queries. Managed here means that the system automates resource provisioning for models to match a set of SLO constraints (cf. autoscaling).
