I've accidentally pushed this into 2.x (no rules violated though) but I'd like to show the run results on my machine (i7 4790, Windows 7 x64, Java 1.8u60)
The backpressure-overhead on range is quite apparent. Naturally, scalar can't do range so I only compared it agains the
justof the others. Single has no equivalent operators for the other cases right now.There is still room for improvement for the range-flatMap-just in NbpObservable and Single.
Again, the lower overhead of NbpObservable shows through in RangeMapRange where there is no fast-path at all and everybody has to subscribe to the inner range.
