been installing a 30gb ark update for 7 hours now, some reason the update was going at my full internet speed then doing an exponential decay until it literally goes to zero and also does the same with disk speed. i have faster internet than my mate but somehow hes installed the entire game faster than this 30gb update. I know its not my internet or pc because i dont get problems using other download platforms and this is the first time this has happened to me on steam. ive cleared download cache and tried changing download region but no luck. Anyone got any Idea?

Steam is very I/O intensive - it downloads encrypted and compressed diff chunks, decrypts them, then decompresses them. Thenafter, Steam stores a backup copy of the file pre-patch before applying the diff (creating another file), then deletes the backup copy.

Download speed is limited by:

* Your storage device's I/O capabilities
* Your CPU
* Your antivirus or other ring 0 kernel driver's (Firewall, device drivers, anti-cheats, ...) I/O efficiency
* Your ISP's peering agreements and infrastructure.

Pick one or multiple.

Regarding ISP, is that why my ISP is showing up in my content log, something about "bad download source," etc.? I've been having trouble downloading and updating games for weeks. I used to just open the content_log, delete the "failed" files or whatever, and then the game would work. Not anymore.

And why would my ISP be blocking me from downloading games on Steam?
