redis-benchmark [ options ]


Redis is an open source (BSD licensed), in-memory data structure store, used as database, cache and message broker, found at

The redis-benchmark command is a command to benchmark redis-server.


-h hostname
Server hostname (default:
-p port
Server port (default: 6379).
-s socket
Server socket (overrides hostname and port).
-a password
Password to use when connecting to the server.
-c clients
Number of parallel connections (default 50)
-dnnum db
SELECT the specified db number (default 0)
-k boolean
1=keep alive 0=reconnect (default 1)
-r keyspacelen
Use random keys for SET/GET/INCR, random values for SADD Using this option the benchmark will expand the string __rand_int__ inside an argument with a 12 digits number in the specified range from 0 to keyspacelen-1. The substitution changes every time a command is executed. Default tests use this to hit random keys in the specified range.
-P numreq
Pipeline <numreq> requests. Default 1 (no pipeline).
If server replies with errors, show them on stdout. (no more than 1 error per second is displayed)
Quiet. Just show query/sec values
Output in CSV format
Loop. Run the tests forever
-t tests
Only run the comma separated list of tests. The test names are the same as the ones produced as output.
Idle mode. Just open N idle connections and wait.


Run the benchmark with the default configuration against
$ redis-benchmark
Use 20 parallel clients, for a total of 100k requests, against
$ redis-benchmark -h -p 6379 -n 100000 -c 20
Fill with about 1 million keys only using the SET test:
$ redis-benchmark -t set -n 1000000 -r 100000000
Benchmark for a few commands producing CSV output:
$ redis-benchmark -t ping,set,get -n 100000 --csv
Benchmark a specific command line:
$ redis-benchmark -r 10000 -n 10000 eval 'return"ping")' 0
Fill a list with 10000 random elements:
$ redis-benchmark -r 10000 -n 10000 lpush mylist __rand_int__
On user specified command lines __rand_int__ is replaced with a random integer
with a range of values selected by the -r option.
