(return status = 0) 1. 解决性能缓慢的问题，需要看最繁忙的时间段的性能数据， 在系统慢的时间段把sar -ud 60 60 /vmstat 60 60
2. 再配合sp_sysmon看，效果比较好
3. 你的服务器和存储配置是什么？ network send 占用了69% , 最有可能是
1、存储过程中有很多的循环处理。
2、返回了一个大结果集。
1的可能性高一点。 Network Packet Received 213.7 1923.0 1923 17.3 %
Network Packet Sent 858.4 7726.0 7726 69.5 %
增加网络包大小，加cpu
