Only ~25k RPS when running benchmark via redis-benchmark

[kamyuentse]

I follow the "Get Started" to build&run GarnetServer, then execute a benchmark via redis-benchmark. The result that ~25k RPS on my machine. Did I miss something?

command: redis-benchmark -t set,get -n 10000000 -p 3278 -c 100 -r 10000000

OS: 20.04.1-Ubuntu
dotnet version: 8.0.202
CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz

1. First, redis-benchmark is known to be extremely heavy on the client side, as it was developed for a different tier of performance.
2. It looks like you have not enabled pipelining which means each request is being fully processed and returned before sending the next in a session. In this mode you are measuring nothing but the performance of localhost network roundtrip time and TCP overhead. Try -P 1024 for example.
3. Either use Resp.benchmark which is carefully designed to ensure client does not become the bottleneck, or if you want a third-party tool then memtier_benchmark (link) is better than redis-benchmark.
