Hi,

I'm not sure what else people read from bonnie++ results but I normally focus on the sequential output block (which I think of as "block write speed" and sequential input block (which I think of as "block read speed"). Smarter folk on this list may be able to provide a more scientific analysis of your results than that though.

In your case, I'm reading the results below as a block write speed of 455 MB/sec and a block read speed of 528 MB/sec which seems pretty good to me (unless my math has failed me). What kind of performance are you expecting?
