I use the itch.io app and whenever I try downloading a game it just tells me 15kb/s or slower, sometimes it goes to 100 or 200 but normally im supposed to download at 500kb/s (yeah my internet reaally sucks).
All of our downloads are served through our CDN. It may not have good coverage in certain regions of the world, but generally it should be pretty fast. The speed you're getting is very slow though. If possible, maybe you could test downloading on another internet connection in your area to see if it makes a difference?
Well, i have the same problem. On my phone it reaches 6Megabytes (not megabits) per second and on PC it's less than 500KB / sec. I'm actually downloading a game and sometimes it can speed up to 1Mb / s but it's rare.
It's very problematic in downloading games. I usually donwload them on phone and then send through USB cable to my PC. but it takes time too...
