BBC bypasses Linux kernel to make streaming videos flow

Back in September, The Register's networking desk chatted to a company called Teclo about the limitations of TCP performance in the Linux stack. That work, described here, included moving TCP/IP processing off to user-space to avoid the complex processing that the kernel has accumulated over the years. It's no surprise, then …
