Is there a limit to the number of virtual hosts or SSL certificates that I can configure in NGINX Plus?

There are no configuration limits for virtual host multi-tenancy, or the number of SSL certificates. The maximum number of configuration objects depends on the server’s RAM.

想想CF，用的就是nginx衍生版，完全不止4090。而且配置多少个网站，只是载入配置文件而以，应该消耗不了多少资源，后面的负载才会对资源有要求。
