# Sample job file demonstrating how to use zoned random distributionss # to have skewed random accesses. This example has 50% of the accesses # to the first 5% of the file (50/5), 30% to the next 15% (30/15), and # finally 20% of the IO will end up in the remaining 80%. [zones] size=2g direct=1 bs=4k rw=randread norandommap random_distribution=zoned:50/5:30/15:20/ # It's also possible to use zoned_abs to specify absolute sizes. For # instance, if you do: # # random_distribution=zoned_abs:50/10G:30/100G:20/500G # # Then 50% of the access will be to the first 10G of the drive, 30% # will be to the next 100G, and 20% will be to the next 500G. # The above applies to all of reads/writes/trims. If we wanted to do # something differently for writes, let's say 50% for the first 10% # and 50% for the remaining 90%, we could do it by adding a new section # after a a comma. # random_distribution=zoned:50/5:30/15:20/,50/10:50/90
