There has been some discussion on the linux kernel mailing list about
providing 2 MB pages (instead of 4kB ones) to user space for the use
of database or scientific calculations.

It seems to me that prime95/mprime would benefit from this enormously
- it should reduce the TLB thrashing to practically zero and hence
speed up mprime by some unknown amount.

Is this true?  Should we put in our plea to the developers?
