C:\Users\admin\Downloads\Redis-x64-3.2.100>redis-benchmark.exe --help
Usage: redis-benchmark [-h <host>] [-p <port>] [-c <clients>] [-n <requests]> [-k <boolean>]

 -h <hostname>      Server hostname (default 127.0.0.1)
 -p <port>          Server port (default 6379)
 -s <socket>        Server socket (overrides host and port)
 -a <password>      Password for Redis Auth
 -c <clients>       Number of parallel connections (default 50)
 -n <requests>      Total number of requests (default 100000)
 -d <size>          Data size of SET/GET value in bytes (default 2)
 -dbnum <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).
 -q                 Quiet. Just show query/sec values
 --csv              Output in CSV format
 -l                 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.
 -I                 Idle mode. Just open N idle connections and wait.

--dbnum

-dbnum

redis-benchmark.c 609 line

} else if (!strcmp(argv[i],"--dbnum")) {
            if (lastarg) goto invalid;

            config.dbnumstr = sdsfromlonglong(config.dbnum);
        } else if (!strcmp(argv[i],"--help")) {

Hi @chengweng,
as mentioned in the official https://github.com/microsoftarchive/redis/blob/3.0/README.md
this project is no longer being actively maintained. If you are looking for an up-to-date alternative, you may want to check out Memurai.

@bettojanea Why should I choose Memurai over https://github.com/tporadowski/redis if I need it for production?

-dbnum was incorrectly specified in help message in version 3.2.100, but always parsed as --dbnum. This was improved later in my updated fork as detailed in this comment to issue tporadowski/redis/#85

@bettojanea Ok, so I now understand better that each project has its own Commercial vs Open source approach and Enterprise support vs Community support. Thanks for your answer.
