Performance Interfaces for Network Functions
Explore a conference talk from NSDI '22 that introduces the concept of performance interfaces for network functions. Delve into how these interfaces can succinctly describe a system's performance, similar to how semantic interfaces describe functionality. Learn about PIX, a tool that automatically extracts performance interfaces from network function implementations. Discover how developers and operators can leverage these interfaces to identify performance regressions, diagnose and fix performance bugs, and assess the latency impact of NIC offloads. Gain insights into the evaluation of PIX on 12 network functions, including production-level examples, and understand how the resulting performance interfaces offer accuracy while being significantly simpler than the original code.
