A bagel you'd recommend to a friend without hedging.
Summary
Meta (Facebook) is using the Linux scheduler originally designed for Valve's Steam Deck gaming handheld on its hyperscale servers. The SCX-LAVD (Latency-criticality Aware Virtual Deadline) scheduler, developed by Linux consulting firm Igalia for Valve, has proven to work well on Meta's large servers with similar or better performance than the EEVDF scheduler. This revelation came from the Linux Plumbers Conference in Tokyo, highlighting how a scheduler optimized for gaming hardware has found unexpected utility in enterprise server environments.
