Linux 3.18: 4 Reasons to Love a ‘Diseased Newt’

A variety of networking performance improvements have been added to the Linux kernel, enabling relatively small systems to drive a high-speed interface at full wire speed, for example, even when small packets are being transmitted.

Small-packet performance has been a problem area for Linux, as developer Jonathan Corbet noted in an early description of the 3.18 merge window, making this a particularly important improvement. “All told, the changes are relatively small,” he explained separately. “But small changes can have big effects when they are applied to the right places.
