At my machine with 8 GB RAM and uptime of 4 days I have page outs of only 2 Megabyte. And page ins of 2 Gigabyte.

What he's saying is happening is that the OS is doing this too aggressively, and that it ends up swapping out data that's actually in use in favor of disk data which doesn't really need to be cached, which hurts performance.
By disabling the pager, you make it impossible to move application data to disk at all. This limits the amount of RAM available for disk caching, but if the OS really is caching too aggressively, that will ensure that it can never page out useful application data by mistake.
My experience mirrors yours, in that it really doesn't seem to be a problem on the computers I've used, but that's what he says he's seeing.
Glad you like the blog, but I'm just a regular guy. I put my pants on with a high speed pants installation robot just like everybody else.
