# ClickHouse Benchmark

> Benchmark and compare ClickHouse queries using server-side system.querylog stats. Use when the user wants to measure query performance, compare old vs new query versions, or analyze duration/memory/bytes-read for a ClickHouse query. Produces P50/P90/P99 latency plus readrows, readbytes, memoryusage, and peakmemoryusage aggregated from system.querylog — no external tools required, just curl + ClickHouse.
