1 | # Sample job file demonstrating how to use zoned random distributionss |
2 | # to have skewed random accesses. This example has 50% of the accesses | |
3 | # to the first 5% of the file (50/5), 30% to the next 15% (30/15), and | |
4 | # finally 20% of the IO will end up in the remaining 80%. | |

13 | # The above applies to all of reads/writes/trims. If we wanted to do | |
14 | # something differently for writes, let's say 50% for the first 10% | |
15 | # and 50% for the remaining 90%, we could do it by adding a new section | |
16 | # after a a comma. | |
