Re-start your server. 重新启动服务器。 For any configuration to take effect, it requires reloading. 为了使任何配置生效，需要重新加载。
It is not for 'concurrent users' it means, how many connections you can open. 它不是针对“并发用户”的，它意味着可以打开多少个连接。
Bandwidth plays an important role. 带宽起着重要作用。 What is the response header that you get? 您得到的响应头是什么？ Are you sure it is MySQL only? 您确定它仅是MySQL吗？ 1000 concurrent users = 1000 concurrent database queries. 1000个并发用户= 1000个并发数据库查询。 What about spooling mechanism? 假脱机机制如何？
What you're trying to do is max_user_connections and NOT max_connections . 您想要做的是max_user_connections而不是max_connections 。 I assumed it when you wrote " *i test my site with 100,200...400 concurrent users respectively but the max_connection cant go high more than 150.* " 当您撰写“ *我分别用100,200 ... 400个并发用户测试我的站点，但max_connection不能超过150个时，我就假定了。”
