CentOS Version: CentOS 7 64bit ? Centmin Mod Version Installed: 123.09beta01 Nginx Version Installed: 1.11.12 PHP Version Installed: 7.1.x MariaDB MySQL Version Installed: 10.1.21 When was last time updated Centmin Mod code base ? : about a week ago I am having some issues on my forum. Some topics are very image heavy and apparently on slower connections they tend to time out. What happens is that if you open the topic with very fast connection everything loads quickly, but if your connection is slow, after some time all unloaded images are listed as broken. Apparently, the slower your connection is, the more images fail to load. Any idea which parameter I can tweak and will it have any detrimental effects on the overall load and speed of the server? I am surprised, because on apache I didn't had such issues and nginx is supposed to be excellent at handing many static files.
