Not completely raw IO devices but those that still keep the page cache active. The results where rather disappointing with a significant reduction in performance.

The VM your playing with is a totally different one. -- <http://www.varnish-software.com/> *Per Buer* CEO | Varnish Software AS Phone: +47 958 39 117 | Skype: per.buer We Make Websites Fly!
