>>> results in a significant performance increase for syscall-bound programs like web servers Reminds me of "Why we use the kernel's TCP stack"? And eternal debate over the performance benefits of "kernel bypass" and "zero-copy" technologies such as DPDK versus full userspace TCP implementations like OpenOnload. https://blog.cloudflare.com/why-we-use-the-linux-kernels-tcp-stack/ https://blog.cloudflare.com/why-we-use-the-linux-kernels-tcp... Conclusion is that the untapped fruit in kernel TCP gains comes from tuning performance of the network stack itself: optimizing overhead a packet incurs on its path through the stack.
