redis2.4与2.6 性能比较

今天在写基于Mysql Binlog刷新redis缓存的项目时，刚完成部分功能开发，整个流程走通了。突然发现测试机自己安装了redis2.4.2与redis2.6.2两个版本，

因此顺手想在测试机上跑下redis相关性能，看有多大的提高：

测试程序是redis自已的redis-benchmark， 参数为：src/redis-benchmark -h host -p port -c 10 -n 100000 -q

Intel(R) Xeon(TM) CPU 2.80GHz 4核，2G内存：

首先是redis2.4.2:

PING_INLINE: 41305.25 requests per second

PING_BULK: 41649.31 requests per second

SET: 42016.81 requests per second

GET: 41788.55 requests per second

INCR: 41823.50 requests per second

LPUSH: 36179.45 requests per second

LPOP: 41067.76 requests per second

SADD: 41823.50 requests per second

SPOP: 41305.25 requests per second

LPUSH (needed to benchmark LRANGE): 41254.12 requests per second

LRANGE_100 (first 100 elements): 17618.04 requests per second

LRANGE_300 (first 300 elements): 6311.94 requests per second

LRANGE_500 (first 450 elements): 4240.16 requests per second

LRANGE_600 (first 600 elements): 3283.75 requests per second

MSET (10 keys): 24667.00 requests per second

redis.2.6.2:

PING_INLINE: 40849.67 requests per second

PING_BULK: 40371.42 requests per second

SET: 41339.39 requests per second

GET: 41118.42 requests per second

INCR: 41169.21 requests per second

LPUSH: 40144.52 requests per second

LPOP: 41580.04 requests per second

SADD: 42069.84 requests per second

SPOP: 42462.84 requests per second

LPUSH (needed to benchmark LRANGE): 41511.00 requests per second

LRANGE_100 (first 100 elements): 17337.03 requests per second

LRANGE_300 (first 300 elements): 6483.82 requests per second

LRANGE_500 (first 450 elements): 4253.15 requests per second

LRANGE_600 (first 600 elements): 2835.27 requests per second

MSET (10 keys): 19047.62 requests per second

从上面两者所跑数据比较来看，基本上相差不大。redis2.6.2 操作性能甚至有细微的下降，有些又有少量的性能增加。

redis2.6.2新功能介绍 中提到了性能相关的主要有一个是AOF性能的提升以及大数据存储时性能提升。因此相关基本操作，redis在之前版本已经很极致了。

以上数据仅供参考！
