1 redis-benchmark Parameter description

Redis Bring their own redis-benchmark It can be for Redis Do benchmark performance testing , The supported parameters are as follows .

-c（clients） Option represents the concurrency of the client （ Default 50）

-n（num） Option represents the number of client requests （ Default 100000）

-q The options just show redis-benchmark Of requests per second Information

-r（random） Options , Can be directed to Redis Insert more random values

-P Options represent each request pipeline The amount of data （ The default is 1）

-k Option represents whether the client uses keepalive,1 For the use of ,0 For not using , The default value is 1

-t Option to benchmark the specified command

–csv Option will follow the result as csv Format output

2 Stress test practice

Experimental hardware conditions ： Under the virtual machine ,8 A processor ,32GB Memory ,600G Hard disk .

Test the following commands respectively ：
（1） PING_INLINE
（2） PING_BULK
（3） SET： String value value Related to key;
（4） GET： return key The string value associated , If key The stored value is not of string type , Return an error ;
（5） INCR： take key The numeric value stored in the is incremented by one . If it cannot be converted to a number, an error will be reported ;
（6） LPUSH： Put one or more values value Insert into list key The header ;
（7） RPUSH： Put one or more values value Insert into list key At the end of the watch ;
（8） LPOP： Remove and return to list key The head element of ;
（9） RPOP： Remove and return to list key The tail element ;
（10） SADD： Put one or more member Elements are added to the collection set among , Existing in a collection member Elements will be ignored ;
（11） SPOP： Remove and return a random element from the collection ;
（12） LPUSH： Put one or more value Insert into list key The header ;
（13） LRANGE_100： Returns a list of key The elements in the specified interval , front 100 Bar element ;
（14） LRANGE_300： Returns a list of key The elements in the specified interval , front 300 Bar element ;
（15） LRANGE_500： Returns a list of key The elements in the specified interval , front 500 Bar element ;
（16） LRANGE_600： Returns a list of key The elements in the specified interval , front 600 Bar element ;
（17） MSET： Set one or more... At the same time key-value Yes ,value For the string .
 

（1）./redis-benchmark -q -n 100000
Run in quiet mode , And only use a single key.

（2）./redis-benchmark -n 100000 -q script load “redis.call(‘set’, ‘foo’, ‘bar’)”
Use direct commands to run .

（3）./redis-benchmark -r 100000 -n 100000 -q
Run in quiet mode , And set up 10 Wan random key.

（4） By default , Each client sends the next request after one request is completed ,benchmark Simulate by default 50 A client , This means that the server reads almost every client's commands in order .
./redis-benchmark -c 10 -r 100000 -n 100000 -q
simulation 10 A client


（5）Redis Support /topics/pipelining, Making it possible to execute multiple commands at one time .Redis pipelining It can improve the performance of the server TPS.
./redis-benchmark -r 100000 -n 100000 -P 200 –q
Pipelining 16 Test of command .
