241 | This tracer helps developers/sysadmins correlate skb allocation and | ||
242 | consumption. The idea being that some processes will primarily consume data | ||
243 | that was allocated on certain numa nodes. By being able to visualize which | ||
244 | nodes the data was allocated on, a sysadmin or developer can optimize the | ||
245 | scheduling of those processes to cut back on cross node chatter. | ||
