Redis: performance test redis-benchmark

Redis performance testing is achieved by executing multiple commands at the same time.

grammar

The basic commands for redis performance testing are as follows:

redis-benchmark [option] [option value]

Note: This command is executed in the redis directory, not the internal instructions of the redis client.

The optional parameters of the redis performance test tool are as follows:

Serial number	Options	description	Defaults
1	-h	Specify the server host name	127.0.0.1
2	-p	Specify server port	6379
3	-s	Specify server socket
4	-c	Specify the number of concurrent connections	50
5	-n	Specify the number of requests	10000
6	-d	Specify the data size of the SET/GET value in bytes	2
7	-k	1=keep alive 0=reconnect	1
8	-r	SET/GET/INCR uses random keys, SADD uses random values
9	-P	Pipe <numreq> requests	1
10	-q	Force redis to exit. Only display query/sec value
11	--csv	Output in CSV format
12	-l	Generate loops and execute tests forever
13	-t	Only run a comma-separated list of test commands.
14	-I	Idle mode. Only open N idle connections and wait.

Run the benchmark test on 127.0.0.1:6379 with the default configuration:

redis-benchmark

Using 2 parallel clients for 127.0.0.1, a total of 500,000 requests:

redis-benchmark -h 127.0.0.1 -p 6379 -n 500000 -c 2

Using only the SET test, fill 127.0.0.1:6379 with approximately 1 million keys:

redis-benchmark -t set -n 1000000 -r 100000000

Benchmark 127.0.0.1:6379, several commands used to generate CSV output:

 redis-benchmark -t ping,set,get -n 100000 --csv

Benchmark a specific command line:

redis-benchmark -r 10000 -n 10000 eval 'return redis.call("ping")' 0

Fill the list with 10,000 random elements:

redis-benchmark -r 10000 -n 10000 lpush mylist rand_int
