I am very impressed with how well written this article is. A brief description of the problem, links to relevant discusions for less informed readers to come up to speed, and clear examples of how key pieces of information were gathered. I learned more from this article about the topic at hand than I have from a Blog post in recent memory.

I'll second this.

The intro was so well written that by the time I got to the first numa_maps output ("2aaaaad3e000 default anon=13240527 dirty=13223315 swapcache=3440324 active=13202235 N0=7865429 N1=5375098") I immediately thought "well geez look at that N0/N1 imbalance, there's your problem right there".

Point being, I haven't dealt with low-level hardware details since college, and yet your article's delightfully clear intro got me sufficiently educated to feel like I was right there with you.

A question well phrased is half answered...
