Pitfalls and Misconceptions of Redis Benchmarking
- Overloading the Server: Benchmarking with an excessively high number of clients or requests can artificially degrade performance. Ensure your benchmarks are realistic.
- Network Overheads: Redis Benchmarking measures not only Redis but also network performance. Latency can be influenced by network conditions.
- Cold Cache vs. Warm Cache: Redis Benchmarking doesn’t account for cache warming. Real-world performance may vary when Redis starts with an empty cache.
- Hardware Variability: Benchmark results can differ significantly based on hardware, CPU, RAM, and disk speed. Ensure consistent hardware for meaningful comparisons.
- Single Operation Benchmark: Redis Benchmarking often focuses on single operations (e.g., SET and GET). Real-world applications involve complex operations.
