While the fact that VictoriaMetrics can handle data ingestion rate at 100 million samples per second for one billion of active time series is newsworthy on its own, the benchmark tool used to generate that kind of load is usually overlooked. The prometheus-benchmark tool has been already mentioned in Benchmarking Prometheus-compatible time series databases and Grafana Mimir and VictoriaMetrics: performance tests blog posts. TSBS tries ingesting the data to the tested system at the maximum possible speed, while the data in production is usually ingested at some fixed speed.
