Slow / weird behavior with download speed

I noticed there is some sort of caching going on between the server and my computer.

Seemingly, downloading with the installer was slow (~200-300KiB), but then trying to download via some other method was fast (10MiB).

However what was really happening, was that re-downloading a file which had already been partially/fully downloaded was fast. There was some sort of caching going on when downloading from the server.

I think there is some issue with downloading very large files (such as the graphics archives) - they are not cached, or perhaps downloading one causes the limited cache to be emptied? so when the next person goes to download, it will need to re-download the file or something). Not sure if the cache is global to everyone, local to regions of the world, or local to just me.

This is not really my area of expertise so I don't really know what could be going on. I also am not sure how we have stuff setup on the server (or how a server is usually setup for serving large files)

检查服务器配置和下载处理代码以了解缓存机制。查看大型文件（如图形存档）的提供方式，以及是否涉及缓存标头或CDN设置。通过新请求与重复请求测试下载速度以复现该问题。
