This commit adds --user for auth in benchmarks. Its purpose is measuring overhead of authentication of v3 API. Of course the given user must be granted permission of target keys before benchmarking. Example of a case with no authentication: % ./benchmark range k1 bench with linearizable range 10000 / 10000 Booooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo! 100.00%2m10s Summary: Total: 130.1850 secs. Slowest: 0.4071 secs. Fastest: 0.0064 secs. Average: 0.0130 secs. Stddev: 0.0079 secs.

It seems that current auth mechanism does not introduce visible overhead.
