Hi,

Do you know if the figures from bonnie++ are able to measure the
performance related to the overhead of the 'fsync' option? I had
very strange performance differences between two Dell 1850
machines months ago, and raw performance (hdparm, not bonnie++)
was similar, the only figure I could find with a significant
difference able to explain the issue was the "await" compound
reported by "iostat" - but I was still very much in the dark :/
