Once we have discovered the Parquet files to be processed, MetaflowDataFrame takes over: it downloads data using Metaflow’s high-throughput S3 client directly to the process’ memory, which often outperforms reading of local files. In other cases, it is more convenient to share the results via a low-latency API.

There is no way to model how much more traffic you can send to that system before it exceeds it’s SLA. Every opportunity for delay due to more work than the best case or more time waiting than the best case increases the latency and they all add up and create a long tail. Mu is the mean of each component, the latency.

Script execution delays interactivity in a few ways: If the script executes for more than 50ms, time-to-interactive is delayed by the entire amount of time it takes to download, compile, and execute the JS. It simulates a link with a 400ms RTT and 400-600Kbps of throughput (plus latency variability and simulated packet loss).

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge.
