The various attributes of the object returned (Benchmark::Tms) are provided here.
Here is a sample application of this in the rails console:
[10] pry(main)> Benchmark.measure { Directory::CountyZipcode.pluck(:state).uniq.sort }
[read] (24.0ms) SELECT `county_zipcodes`.`state` FROM `county_zipcodes`
=> #<Benchmark::Tms:0x007fa731d4e8a8

@total=0.16999999999999726,
@utime=0.13999999999999702>
[11] pry(main)> Benchmark.measure { Directory::CountyZipcode.select(:state).order(:state).distinct.map(&:state) }
[read] Directory::CountyZipcode Load (35.3ms) SELECT DISTINCT `county_zipcodes`.`state` FROM `county_zipcodes` ORDER BY `county_zipcodes`.`state` ASC
=> #<Benchmark::Tms:0x007fa7372831c0
