For me, this article is very reassuring. My server used to be at <0.8% cpu usage. Now that I installed mongodb with almost nobody using my app (< 2 person per hour), my cpu is always at ~1.6% (It doubled because of mongodb!). At first, I feared that my cpu use would be enormous as soon as I would get new users. Now I guess my cpu% increase is due to some overhead that will not grow too much with db size/use (if the author was able to make an app of this scale with mongodb). I'll also try the lean() mongoose thing.
