Performance (Small Collections)

Following performance tests were performed on simple, enumerable collection generated by Enumerable.Range(0, collectionSize). Partial times, longer than normalized deviation, were discarded.
###Settings

• Collection size: 10

• Sample size: 50

• Iterations per sample: 1,000,000
  ##NSlice vs. LINQ
  ###Get items at odd indices -7.8%

• .Slice(1, step: 2).Last()
  218 ms

• .Where((x, i) => i % 2 == 1).Last()
  236 ms

###Reverse

• .Slice(step: -1).First()
  296 ms

• .Reverse().First()
  286 ms

###Reverse and get at even indices -25.3%

• .Slice(step: -2).Last()
  388 ms

• .Reverse().Where((x, i) => i % 2 == 0).Last()
  519 ms

###Get middle terce

• .Slice(terce, terce*2).Last()
  184 ms

• .Skip(terce).Take(terce).Last()
  187 ms

###Get middle terce reversed -7.0%

• .Slice(-terce, terce, -1).First()
  241 ms

• .Skip(terce).Take(terce).Reverse().First()
  259 ms
