--max-requests=N limit for total number of requests [10000]
如果这里不指定--max-requests，默认为10000，就是执行1W次操作就结束了，如果要做压力测试的话，就需要手动设置此值。
[b]--num-threads=N number of threads to use [1] (clients to access mysql db)
这里指的是有多少个mysql clents来访问mysql服务器，用show full processlist就可以看到大概的记录数。[/b]

报这个错误，是因为数据没有，7.8.1没有执行，需要重新录入测试数据。

看到这里，大leader说这个数值偏高了，在game领域，最好<10ms，并且他猜测我是local测试的，local500个线程也许会
[b] 对db server有一些压力的，建议我remote测试访问测试下看[/b]
7.8.1 混合读写测试 远程读写数据准备，远程跑后台进程准备数据。

报这个错误，是因为数据没有，7.8.1没有执行，需要重新录入测试数据。
后续准备做mysql的性能监控工具。
