I think that you should use my tool to measure I/O performance.
Because I want to see the mins, maxes, average and
std dev. Iozone adds way too much noise to the data. You can run it 5
times in a row and get completely different numbers. Please use
https://github.com/andreiw/superalign.
For a more realistic test you can try performing 20000 sqlite inserts
or something of the sort and timing that.
