Description
We have a lot of CS tickets / consulting engagements that end in needing to adjust (usually turn down) disk readahead.
We should have some documentation around the affects of disk read-ahead, how to view and change it, and when it's a good idea to do so.
We should also have a page "Why isn't mongo using all available RAM?" that links to this page.
