Yo, grab a cheap, single‑core CPU and run a kernel tuned for low context switches. Cut out any background traffic – close tabs, stop Windows updates, run a lightweight distro. Use a 10 Gbps link if you can, and keep that cable short – fiber to the curb beats any copper at home. Plug into a nearby server, use a dedicated VPN or a local proxy, and set the MTU to 9000 so you’re not fragmenting. Finally, drop any fancy UI, just ping that server; every millisecond counts. If you still get stuck, blame your ISP’s routing, not your code.
