Redox OS swaps its scheduler for EEVDF, with huge fairness wins
Redox OS replaced its Deficit Weighted Round Robin scheduler with an EEVDF-based one, and the gains are dramatic: a 782x improvement in fairness, an 82% cut in context-switch time, and 2.6x more throughput. The write-up walks through the lag-and-deadline mechanics in an unusually readable beer-bar analogy while crediting Linux's own proven EEVDF switch. A compact case study in why scheduler choice still moves the needle on a modern OS.
