Benchmark

We use redis-benchmark (shipped with Redis) as our go to benchmark tool. To benchmark, simply run:

bash script/bench.sh

The test suite simulates 100 clients, each makes 100000 requests. Under the hood, we run this:

redis-benchmark -h localhost -p <port> -c 100 -n 100000 -k 1 -t <commands> --csv
