anticipatory I/O scheduling

[Dag-Erling Smørgrav]

I just ran across this paper and started wondering why I'd never heard
of it before:

<URL:http://www.cs.rice.edu/~ssiyer/r/antsched/>

To summarize, the authors rewrote the I/O scheduling algorithm in
FreeBSD 4.3 and got massive performance improvements for Apache, and
smaller but noticeable improvements for AFS and TPC-B.

Has anyone looked into this?
