Config:

Sentry.config(Config.SENTRY_DSN, {deactivateStacktraceMerging: true}).install();

I have following issue:

If I use raven-js, I don't see any problem. Whenever I link sentry to start tracking native events, the performance of the app drops. I see frames being dropped for pretty much every action I dispatch (I use react-redux) and also nav transitions (react-navigation).

I have tried to deactivate the merging of the stacktrace, but I don't see much difference. I have tried both debug and release environments. I have no idea what could be conflicting here and I can understand this bug report is not really clear.

Steps to reproduce:

• Two actions dispatched to refresh a scrollview or a simple navigation transition.

Actual result:

• All the frames dropped and lag on the refresh animation.

Expected result:

• 60 frames per second

Hey, are you running your app in DEV?
If so try running in in RELEASE, also if you have time can you maybe try this branch and see if it fixes your problem:
#282

It's just changes in RNSentry.m so you could copy the content and replace it locally and try if the performance issues are still there.

@HazAT I tried both Release and Dev. I will give the branch a go, thanks!

It is already released 0.30.0
