Bug 2122374

.The `-W` and `--bucket-width` options have been added to the `oslat` program to measure latency With this enhancement, you can specify a latency range for a single bucket at nanosecond accuracy. Widths that are not multiples of 1000 nanoseconds indicate nanosecond precision. By using the new options, `-W` or `--bucket-width`, you can modify the latency interval between buckets to measure latency within sub-microseconds delay time. For example to set a latency bucket width of 100 nanoseconds for 32 buckets over a duration of 10 seconds to run on CPU range of 1-4 and omit zero bucket size, run the following command: ---- # oslat -b 32 -D 10s -W 100 -z -c 1-4 ---- Note that before using the option, you must determine what level of precision is significant in relation to the error measurement.
