The problem in context of the presentation linked to is optimizing IOPS for MySQL workloads. The "solution" (spoiler warning) for them, is moving from DAS to NAS using the shiny new Sun S7410 storage system.

Regarding your remarks, I share your appreciation, especially of XFS. I've done some benchmarking on a workload that involves roughly 2 million pretty small files, and all ext3 managed was coughing in the dust left behind by XFS (XFS being ~30× faster in one use case, as far as I remember).
