Google's BPF-CCX Scheduler Unlocks Higher AMD Zen Performance in Linux
Google has developed BPF-CCX, an innovative Linux scheduler leveraging eBPF for optimized thread placement across AMD Zen core complexes. Benchmarks presented at Linux Plumbers Conference 2025 show significant gains over the default EEVDF scheduler, particularly for virtualized workloads. This approach marks a strategic shift in CPU resource management for EPYC servers and Ryzen systems.
