If you only eat one bagel today, this is the bagel.
Summary
The article details the implementation of a new CPU scheduler for Redox OS, replacing the legacy Round Robin scheduler with a Deficit Weighted Round Robin scheduler. This modernization effort, funded through the Redox Summer of Code program, introduces priority assignment capabilities for process contexts. While light loads may show minimal differences, the new scheduler demonstrates superior performance under heavy system loads, marking a significant improvement in the operating system's process management subsystem.
