Redux-observable: Extremely slow & barely usable

[pawelotto]

Did you even run performance tests on this? When I'm using this to map actions the target action is executed like 0,7 seconds after the source has action dispatched. On the other hand, when I subscribe directly to the same store variable using RxJS's from() method it takes only 1 ms to dispatch the consecutive action.

This alone makes this plugin virtually useless.

No one has ever run any of the code in this repo. We're not even sure where the code came from, to be honest.

In seriousness, I suggest taking a less abusive approach to people who volunteer their time and code. We're friendly people to people who are friendly.

It's unclear exactly what you were doing to run into performance concerns, but here's a simple "hello world" of performance tests—it also includes the intrinsic overhead from Redux and RxJS. If you're able to create a minimum reproduction I can take a look.

Here is an idea. Why don't you make your own library that operates to your own liking?
