【压测环境】

操作系统：Ubuntu 14.04 LTS

Linux版本：3.13.0-24-genericx86_64GNU/Linux

处理器：4核的AMD Athlon(tm) II X4 640Processor @800MHz

机器内存：共 8GB，已使用 6GB，未使用 2GB，交换区 未使用

Redis版本：2.8.17

Redis内存：500MB

【压测结果】

压测原生的 Redis 性能(非Java客户端)，结果如下：

hset和hget都能在4ms之内完成，且每秒并发处理量都在7.5万个请求之上；

hmset和hmget一次操作两个数据，都能在5ms之内完成，且每秒并发处理量都在7.1万个请求之上。
