start the server with this config

redis-server --save "" --appendonly no --latency-monitor-threshold 100

    # when to save db on disk :
    # after 60 seconds if at least 1000 key changed
    - "--save"

test latency

run a big benchmark :

docker exec redis redis-benchmark -q -n 100000

see latency :

docker exec redis redis-cli latency doctor
docker exec redis redis-cli latency latest

manual latency test

docker exec redis -ti redis-cli
127.0.0.1:6379> debug sleep 1
127.0.0.1:6379> debug sleep .25
127.0.0.1:6379> latency latest
1) 1) "command"
2) (integer) 1405067976 # timestamp
3) (integer) 251 # latest latency
4) (integer) 1001 # worse latency
