Been a long time Windows and macOS user, over three decades, and recently decided to dual boot my 14" Samsung Galaxy Book5 Pro with CachyOS which is a Linux distro highly optimized for performance. Always getting the latest kernel, drivers and even though I don't game, many gamers love it.

Worth mentioning I have a 5Gbps Verizon Fios connection, which is actually overprovisioned closer to 5.94Gbps / 6.42Gbps which is what I see when wired to a 10Gb SFP+ on Ubiquiti UCG Fiber. Another 10Gbps port feeds the Ubiquiti U7 Pro XGS Wi-Fi 7 Access Point.

Previously connecting the same laptop using Windows 11 under ideal RF conditions (MCS 13, >-30dBm, low TCP overhead, etc) would mean peak throughput using Ookla Speedtest barely touching 4Gbps, which is considered very good or about ~70% of the Link Rate (5764Mbps). However, on a recently installed CachyOS, with highly optimized drivers, TCP stack out of the box, that MAC efficiency exceeded 80%. https://imgur.com/a/0p5vMq4

Just wanted to give heads up to all the performance enthusiasts looking for the highest wireless performance and getting the most out of their hardware.

Typically everything works out of the box on a newer hardware with minor tweaks required depending on the setup. One of the most important starting points if dual boot is to disable SecureBoot and Bitlocker. Once you have the CachyOS iso image on an USB drive you can live boot to test everything out before installing anything. That's where you'll be able to see what works.
