> Throughput stays flat and latency grows linearly
In production I observed somewhat different behaviour. The convoy effect
was noticeably stronger under CPU-bound work. We found that past ~40% CPU
utilisation, response-time degradation became non-linear, so we had to
keep CPU usage below that threshold.
