Provide more latency data in results #68
Description
Hi memtier_benchmark developers,
Currently memtier_benchmark can report average latency in the results, which is usually enough for simple benchmarks. it also provides the option to print the detail latency distribution. The data is aggregated through different latency level. However for storage/DB performance, people will also care about the tail latency(99%, 99.9% or 99.99%, example from fio). Is it possible to provide these tail latency data also?
