How to Stress Test Redis with redis‑benchmark: Commands, Parameters, and Results

Many people install and deploy Redis without performing performance testing on its configuration and high‑availability setup, which can lead to cache penetration, avalanche, and other issues. As operations staff, you can use Redis's built‑in benchmark tool for simple load testing. redis-benchmark [option] [option value] For example, with a local Redis service at IP 10.100.81.171, you can simulate 100 concurrent users each performing 1000 requests.

redis-benchmark -h 10.100.81.171 -p 6379 -c 100 -n 100000

Parameter details:

100000 requests completed in 1.60 seconds (default 100000)

3 bytes payload per request

keep alive: 1 (single connection handling all requests)

100.00% ≤ 2 milliseconds latency

62656.64 requests per second throughput

You can also monitor Redis server resource usage with monitoring commands or other tools:
