Huge performance penalty because of immutable props validation

NODE_ENV=production disables React’s PropTypes but not ImmutablePropTypes. After manually removing them I got a 75%(!!!) rendering speed improvement.

I’m using stuff ranging from

let somePropType = ImmutablePropTypes.mapContains({
    id: PropTypes.string.isRequired,
    name: PropTypes.string.isRequired,
    isProjectLeader: PropTypes.bool,
    isHidden: PropTypes.bool,
    projectLeaderColor: PropTypes.string,
    index: PropTypes.number
});

to

let listOfSomePropType = ImmutablePropTypes.listOf(somePropType).isRequired

Is there a way for me to disable validation in production?

What version of React are you on? Also how are you doing the profiling? Just curious how you came to the conclusion that React was actually running the validation logic. I don’t think I have seen this issue yet in my usage.

Performance penalty comes from the actual validation. When you have an Immutable List of Maps of a certain shape the validation process is at least half of re-rendering time.
