请教大神帮忙分析：生成随机数插入很慢，5个索引算多吗？
本帖最后由 jimy1 于 2017-5-4 10:56 编辑go语言写的for循环，每次循环生成5个值（对应5个索引字段）加上25个固定值拼成SQL语句，执行插入。
不加索引（30字段，也是循环生成随机值插入）用/mysqladmin -u -p extended-status -r -i1|grep -i Com_insert查看结果平均在3000每秒，插入100万数据时间为5分钟多一点：
sudo/usr/bin/mysqladmin -u -p extended-status -r -i1|grep -i Com_insert
| Com_insert | 1022904 |
| Com_insert_select | 0 |
| Com_insert | 2318 |
| Com_insert_select | 0 |
| Com_insert | 4003 |
| Com_insert_select | 0 |
| Com_insert | 2572 |
| Com_insert_select | 0 |
| Com_insert | 2050 |
| Com_insert_select | 0 |
| Com_insert | 3956 |

| Com_insert_select | 0 |
| Com_insert | 4556 |
| Com_insert_select | 0 |
| Com_insert | 4584 |
| Com_insert_select | 0 |
加了5个索引后，用/mysqladminextended-status |grep Com_insert 查看每秒在300-600间，插入100万数据为30分钟。（最开始1分钟能到2000左右每秒的插入量）
sudo/usr/bin/mysqladmin -u -p extended-status -r -i1|grep -i Com_insert
| Com_insert | 29941 |
| Com_insert_select | 0 |
| Com_insert | 2566 |

MySQL是5.7.12版本，操作系统是红帽6.1，我感觉太慢了，请各位大神帮忙分析下，谢谢了
代码（50万数据）：

go insertUnis(db,"unis") //500个go程

return nil
}
func insert(db *sql.DB, name string){

user_name := string(Krand(64,0)) //生成64位的随机数
session_key:=string(Krand(56,0)) //生成56位的随机数
