# Redis Benchmarks - Đo hiệu năng của Redis Redis benchmark là công cụ để thực hiện đo tốc độ xử lý đồng thời của Redis database. **Cú pháp:** ```shell redis-benchmark [option] [option value] ``` Ví dụ: Thực hiện đồng thời 100000 lệnh ```shell redis-benchmark -n 100000 PING_INLINE: 141043.72 requests per second PING_BULK: 142857.14 requests per second SET: 141442.72 requests per second GET: 145348.83 requests per second INCR: 137362.64 requests per second LPUSH: 145348.83 requests per second LPOP: 146198.83 requests per second SADD: 146198.83 requests per second SPOP: 149253.73 requests per second LPUSH (needed to benchmark LRANGE): 148588.42 requests per second LRANGE_100 (first 100 elements): 58411.21 requests per second LRANGE_300 (first 300 elements): 21195.42 requests per second LRANGE_500 (first 450 elements): 14539.11 requests per second LRANGE_600 (first 600 elements): 10504.20 requests per second MSET (10 keys): 93283.58 requests per second ``` **Các tham số:**

Sr.No	Option	Description	Default Value
1	-h	Specifies server host name	127.0.0.1
2	-p	Specifies server port	6379
3	-s	Specifies server socket
4	-c	Specifies the number of parallel connections	50
5	-n	Specifies the total number of requests	10000
6	-d	Specifies data size of SET/GET value in bytes	2
7	-k	1=keep alive, 0=reconnect	1
8	-r	Use random keys for SET/GET/INCR, random values for SADD
9	-p	Pipeline <numreq> requests	1
10	-h	Specifies server host name
11	-q	Forces Quiet to Redis. Just shows query/sec values
12	--csv	Output in CSV format
13	-l	Generates loop, Run the tests forever
14	-t	Only runs the comma-separated list of tests
15	-I	Idle mode. Just opens N idle connections and wait

**Ví dụ:** ```shell redis-benchmark -h 127.0.0.1 -p 6379 -t set,lpush -n 100000 -q SET: 146198.83 requests per second LPUSH: 145560.41 requests per second ```
