How Linux io_uring and eBPF Transform Network Performance

In episode 158 of The Linux Podcast with Fexingo, Lucas and Luna dig into the real-world impact of combining io_uring with eBPF for high-speed networking. They unpack how these two kernel technologies work together to slash latency and boost throughput, using the example of a hypothetical CDN edge server handling millions of requests. The conversation covers the mechanics of both systems, the challenges of integration, and practical advice for developers looking to experiment. They also touch on the broader trend of kernel-bypass alternatives and why io_uring and eBPF are becoming the go-to for performance-critical applications. A concrete, accessible look at cutting-edge Linux internals.
