API and infrastructure load testing is emphasizing realistic workloads and tail latency

Gatling guidance demonstrates chained authentication, varied data feeders, open workload modeling, percentile analysis, and CI assertions for API performance automation. Django-Bolt benchmarking reinforces that synthetic throughput is insufficient: authentication, database work, serialization, CPU cost, and tail latency must be represented. Envoy benchmarking adds realistic configuration, correct worker and connection distribution, open-loop load, below-saturation latency measurement, statistical validation, and flame graphs.
