这是一个多线程c++redis服务器和客户端。
单核心的公开环境不到100k：redis整体性能比xredis快10-25％qps（因为使用STL和xredis的内存管理成本线程安全）内核瓶颈80-90％cpubenchmark.pdf
Redis速度有多快？
Redis包含了一个redis-benchmark实用程序，它可以模拟N个客户端执行的运行命令，同时发送M个总查询（类似于Apache的ab实用程序）。
在下面你会发现一个基于Linux基准测试的完整输出。
支持以下选项：
Usage: redis-benchmark [-h <host>] [-p <port>] [-c <clients>] [-n <requests]> [-k <boolean>] -h <hostname> Server hostname (default 127.0.0.1) -p <port> Server port (default 6379) -s <socket> Server socket (overrides host and port) -a <password> Password for Redis Auth -c <clients> Number of parallel connections (default 50) -n <requests> Total number of requests (default 100000) -d <size> Data size of SET/GET value in bytes (default 2) --dbnum <db> SELECT the specified db number (default 0) -k <boolean> 1=keep alive 0=reconnect (default 1) -r <keyspacelen> Use random keys for SET/GET/INCR, random values for SADD Using this option the benchmark will expand the string __rand_int__ inside an argument with a 12 digits number in the specified range from 0 to keyspacelen-1. The substitution changes every time a command is executed. Default tests use this to hit random keys in the specified range. -P <numreq> Pipeline <numreq> requests. Default 1 (no pipeline). -q Quiet. Just show query/sec values --csv Output in CSV format -l Loop. Run the tests forever -t <tests> Only run the comma separated list of tests. The test names are the same as the ones produced as output. -I Idle mode. Just open N idle connections and wait.
