这次分别测试，正常启动redis，taskset启动redis帮顶第二个cpu，docker启动redis这3种情况
redis 版本 2.8.19
redis配置都用默认的配置，如下：
daemonize yes
port 6379
1、正常启动redis
启动命令：redis-server /etc/redis.conf
性能测试命令：redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100

2、利用 taskset 帮顶一个cpu启动redis
启动命令：taskset -c 01 redis-server /etc/redis.conf
性能测试命令：redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100
PING_INLINE: 54377.38 requests per second
PING_BULK: 71530.76 requests per second
SET: 68681.32 requests per second
GET: 67659.00 requests per second
INCR: 71839.09 requests per second
LPUSH: 68870.52 requests per second
LPOP: 71479.62 requests per second
SADD: 68027.21 requests per second
SPOP: 55741.36 requests per second
LPUSH (needed to benchmark LRANGE): 66711.14 requests per second
LRANGE_100 (first 100 elements): 29877.50 requests per second
LRANGE_300 (first 300 elements): 12230.92 requests per second

INCR: 65019.51 requests per second
LPUSH: 65104.17 requests per second
LPOP: 62266.50 requests per second
SADD: 70771.41 requests per second
SPOP: 67980.97 requests per second
LPUSH (needed to benchmark LRANGE): 66666.66 requests per second
LRANGE_100 (first 100 elements): 13051.42 requests per second
LRANGE_300 (first 300 elements): 4299.41 requests per second
LRANGE_500 (first 450 elements): 2699.27 requests per second
LRANGE_600 (first 600 elements): 1668.72 requests per second
MSET (10 keys): 31387.32 requests per second
3、时候用 docker 正常启动 redis
启动命令：
docker run -v /myredis/conf/redis.conf:/usr/local/etc/redis/redis.conf -p 6379:6379 –name myredis -d redis:2.8.19
性能测试命令：redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100
PING_INLINE: 9511.13 requests per second
PING_BULK: 11918.95 requests per second
SET: 11184.43 requests per second
GET: 12239.90 requests per second
INCR: 8203.45 requests per second
LPUSH: 10544.07 requests per second
LPOP: 10288.07 requests per second
SADD: 12119.74 requests per second
SPOP: 10296.54 requests per second
LPUSH (needed to benchmark LRANGE): 9562.06 requests per second
LRANGE_100 (first 100 elements): 7514.28 requests per second
LRANGE_300 (first 300 elements): 4647.92 requests per second
LRANGE_500 (first 450 elements): 2856.49 requests per second
LRANGE_600 (first 600 elements): 2484.41 requests per second
MSET (10 keys): 10114.29 requests per second
下面500的不用测试了
总结一下，docker之后对性能的影响比较大，使用taskset可以稍微提升redis的性能
