I made some significant revisions to the entry to include each of the four IO schedulers: cfq (what I originally used), anticipatory, deadline, and noop, removed the 128K chunk size and added 2048K (at Neil Brown's suggestion), and re-did the graphs using google charts. If anybody has any trouble viewing it please contact me OFF-LIST or add a comment to the blog. I actively welcome comments and suggestions.
