From practical experience, I find it a bit hard to believe this is actually how it works for latency. Were any specific examples provided?

- jiggawatts 5y agoLots of examples. Typically the issue was caused by garbage collection. You can twiddle with the parameters to meet your 99% latency goal, and then fail your 1% spectacularly. Similarly, anything involving the network would slowly be optimised to meet the "typical case" requirements, while the extremes would be terrible. If I remember correctly, this was a talk by someone working in a real-time trading firm, where latency was a critical metric for all of their systems designs. He had a lot of charts with very visible upticks in latency at the "nice round numbers" where the requirements were set.
