UnverifiedIf the P99 latency of a single service is 1 second, the probability that a call triggering 5 parallel sub-requests encounters at least one exceeding P99 latency is approximately 5% (1 - 0.99^5).79% similarUnverifiedFor interactive search, P99 latency typically needs to be kept within a few hundred milliseconds.78% similarUnverifiedIn testing, the p99 latency per 160-millisecond tick was 147.4–147.5 milliseconds, with zero missed deadlines across three rounds totaling 84,000 session ticks measured.70% similarUnverifiedGoogle's RAIL model indicates that users' perceptual threshold for response latency is approximately 100ms to 1000ms, and exceeding 3 seconds will most likely cause them to abandon waiting.70% similar
