@dolphinux - check out https://github.com/facebook/react-native/blob/60b56455c4b30cbd0cb29790a7751329576ae8d6/React/Base/RCTBatchedBridge.m#L268-L273 - notice that this is passed in to both RCTPerformanceLogger and RCTProfile - does that help?

Have a look at the Inspect Element tool, specifically in the Perf tab, that will have the data for you!
