Google has recently developed and demonstrated "BPF CCX," a new scheduling mechanism designed to extract more performance from AMD Zen-based systems. This solution utilizes the Linux kernel's extended Berkeley Packet Filter (eBPF) capabilities, working in tandem with a user-space agent. Its core function is to optimize thread placement on modern AMD processors, specifically addressing systems configured with multiple CPU core complexes. Google has reported "very positive performance results" from this approach, indicating that it leads to greater overall performance on AMD processors running under Linux by improving high-performance scheduling.
