+## 参数
+所有的命令行参数如下所示：
+```
+  -command (command to execute, eg: generate/get/set/zadd) type: string default: "generate"
+  -compare_value (whether compare result or not) type: bool default: false
+  -count (request counts per thread) type: int32 default: 100000
+  -dbs (dbs name, eg: 0,1,2) type: string default: "0"
+  -element_count (elements number in hash/list/set/zset) type: int32 default: 1
+  -host (target server's host) type: string default: "127.0.0.1"
+  -key_size (key size int bytes) type: int32 default: 50
+  -password (password) type: string default: ""
+  -port (target server's listen port) type: int32 default: 9221
+  -thread_num (concurrent thread num) type: int32 default: 10
+  -timeout (request timeout) type: int32 default: 1000
+  -value_size (value size in bytes) type: int32 default: 100
+```
+
+compare_value: 是否进行数据校验。如需进行数据校验，set和set操作都需要设置为true。如果compare_value为true，执行set命令时的value值即为key值拼接得到，如果哦compare_value为false，value为随机值。
+
+count: 每个线程请求的key个数。
+
+element_count: list/zset/set/hash 每个pkey下的member个数。
+
+目前支持的command包括：get,set,hset,hgetall,sadd,smembers,lpush,lrange,zadd,zrange
+
+## 使用方式
+需要先执行generate方式生成待请求的key，如：
+```
+./benchmark_client --command=generate --count=2 --element_count=10 --port=9271 --thread_num=2 --key_size=10 --value_size=25 --host=127.0.0.1 --compare_value=1
+```
+执行完成后会在当前目录生成两个benchmark_keyfile_*文件（每个线程生成一个），每个文件行数为20（element_count * count），每个key长度为10.
+
+接下来可以执行redis API命令，命令执行时，会首先从benchmark_keyfile_*文件中读取到key，在根据compare_value值设置value值。
+
+set命令：
+```
+./benchmark_client --command=set --count=2 --port=9271 --thread_num=2 --key_size=10 --value_size=25 --host=127.0.0.1 --compare_value=1
+```
+
+get命令：
+```
+./benchmark_client --command=get --count=2 --port=9271 --thread_num=2 --key_size=10 --value_size=25 --host=127.0.0.1 --compare_value=1
+```
+
+hset命令：
+```
+//将向pika写入共4个hash pkey，每个pkey包含10个member。
+./benchmark_client --command=set --count=2 --element_count=10 --port=9271 --thread_num=2 --key_size=10 --value_size=25 --host=127.0.0.1 --compare_value=1
+```
+
+hgetall命令：
+```
+./benchmark_client --command=hgetall --count=2 --element_count=10 --port=9271 --thread_num=2 --key_size=10 --value_size=25 --host=127.0.0.1 --compare_value=1
+```
+
+## 执行结果
