Clarifications

[bolds07]

First of all good job, i really appreciated your comparsion it helped me a lot but i woud like to suggest a few fixes on the presentation of the results

After you describe the test cases and put the result table, you should inform which unity represents the informed value and WHAT IS THE DESIRED VALUE (lower better)

Your two first columns are read and write... at first sight i thought those numbers represented the number of operations something like IO/time, in which case high numbers are better.

It took me few minutes, scroll up and down until i notice the histograms and realize that those numbers meant the total time to realize the batch of operations
