See also a very nice video from ClojureWest about queues in system architectures: https://www.youtube.com/watch?v=1bNOO3xxMc0 The queue are everywhere - your messaging queue, the threadpool, the hardware threads, and other layers of the stack and APIs you use. The video adds the interesting detail that as you add more tellers (workers) you learn of impending disaster only in the outlier p99 (or higher) latencies; by the time your p85 latency rises, you're already about to stall out. |
