Downloading Games at 10 GIGABIT?

Linus Tech Tips explores a hardware and software solution to drastically improve game downloading speeds inside a shared network, targeting situations where many people pull large titles simultaneously. The video explains the core idea of caching servers that store downloaded game data on a dedicated machine, so future requests can be fulfilled locally instead of pulling from external servers. The team discusses practical hardware choices, including a 10 gigabit network interface card and a RAID zero array of Corsair SSDs, to create a high-throughput caching host. They also cover the software stack, focusing on a Docker-based steam cache setup that can manage multiple caching services such as Steam, Origin, Battle.net, and Uplay, all running in separate containers for efficiency and scalability. The host network and DNS configuration steps are outlined, with an emphasis on using a caching DNS to forward requests to the local server and reduce external bandwidth. In the test phase, the video demonstrates real-world results showing sub-second initial downloads and sustained multi-user speeds, with peak observed rates around several gigabits per second depending on the workload and hardware constraints. The presenters also provide a balanced view, noting that for many casual users the built-in Steam backup and NAS solutions might be more user-friendly, while a robust LAN or data-center setup can benefit from this caching approach for multiple simultaneous users and large titles. Finally, the video closes with practical considerations about hardware redundancy, the non-critical nature of the caching server, and invites viewers to imagine future demos or a more advanced LAN setup, inviting feedback on follow-up experiments.
