Improve `ActiveSupport::Duration` performance about 25% ~ 50% `ActiveSupport::Duration` expects `parts` as a Hash in the internal, but sometimes that is passed as nested array. (e.g. `parts.map { |type, number| [type, number * other] }`) By avoiding the extra array allocation, it makes `ActiveSupport::Duration` performance faster about 25% ~ 50%. ```ruby Benchmark.ips do |x| x.report("4.seconds + 2.seconds") { 4.seconds + 2.seconds } x.report("4.seconds - 2.seconds") { 4.seconds - 2.seconds } x.report("4.seconds * 2") { 4.seconds * 2 } x.report("4.seconds / 2") { 4.seconds / 2 } end ``` Before (e36d4a03): ``` Warming up -------------------------------------- 4.seconds + 2.seconds 27.515k i/100ms 4.seconds - 2.seconds 20.783k i/100ms 4.seconds * 2 40.286k i/100ms 4.seconds / 2 41.717k i/100ms Calculating ------------------------------------- 4.seconds + 2.seconds 299.133k (±13.4%) i/s - 1.486M in 5.053953s 4.seconds - 2.seconds 222.476k (± 9.8%) i/s - 1.122M in 5.088532s 4.seconds * 2 479.650k (±10.5%) i/s - 2.377M in 5.008644s 4.seconds / 2 473.768k (±11.3%) i/s - 2.378M in 5.082413s ``` After (this change): ``` Warming up -------------------------------------- 4.seconds + 2.seconds 35.856k i/100ms 4.seconds - 2.seconds 28.657k i/100ms 4.seconds * 2 51.744k i/100ms 4.seconds / 2 51.417k i/100ms Calculating ------------------------------------- 4.seconds + 2.seconds 445.972k (±21.6%) i/s - 2.080M in 5.018570s 4.seconds - 2.seconds 317.972k (±18.2%) i/s - 1.519M in 5.006564s 4.seconds * 2 608.695k (±12.8%) i/s - 3.001M in 5.014321s 4.seconds / 2 611.488k (±12.0%) i/s - 3.034M in 5.035211s ```
