加特林。 ConnectException：连接超时：
Gatling. ConnectException: connection timed out:
我是加特林的新手，现在正在其网站计算机上试用加特林-database.gatling.io。
一切正常，几天后我将在工作中对我的项目进行负载测试，但有一个问题，
我的网站需要 2000 users/per 秒（正如我在其他资源上看到的那样，对于 gatling 来说似乎没什么大不了的）
我有这个简单的代码：我想在 300 秒内加载 250 users/admins，现在问题和问题（请帮我解决这个问题）

我想这可能与我的问题有关，或者我做错了什么？是我的问题还是他们的网站无法接受？
为什么我启动时
users.inject(constantUsersPerSec(200) during (300 seconds)),
admins.inject(constantUsersPerSec(50) during (300 seconds))

constantUsersPerSec() 是关于您注入的用户数，而不是总用户数。
constantUsersPerSec(200) during (300 seconds)，即 6 万用户。因此，这与 waiting: 55156 / active: 4842 / done:2= 60k 用户匹配。
我认为您真正想要的是使用以下策略注入用户：rampUsers(10) over (300 seconds)
