Hi Shai,
I totally agree the comparison with Rx implementation may look odd. The reason it's there in the first place, is because we use RxSwift for several projects at Google and there was an internal request to compare the performance of the two, after we had the initial data for all other popular promises implementations.
To address that request we tried to write performance tests for RxSwift in such a way that they would imitate A+-style promises as close as possible, so we had to use Subjects
. Using any other type of Observable
lead to 2x and more performance downgrade in our experience.
Here's a snippet you can add to performance tests to reproduce our results.
Please, let us know if there's a better way to compare the two at least in such a limited way.
Many thanks for the great question!

Hey @shoumikhin, I really appreciate you answering so promptly, and It's exciting to know RxSwift is used internally on some Google projects.
I'll close this issue for now and will comment back if there are any new findings regarding this :)
Thanks!
