But sometimes, we’ll encounter a bug or performance issue that comes directly from the Android runtime. Since most of the performance problems originate from the JS realm, we don’t usually need to do anything beyond that. In the event of any performance issues, we mostly use React Profiler to troubleshoot and resolve our problems. We don’t see the doFib function anymore, only other expected RN tasks. You can monitor the CPU, Memory, and Network. Xcode provides some basic tools to do the first report.
Getting all this information helps you to track down and provide proper solutions to keep your app healthy and your users engaged. Profiling is essential to understanding the runtime performance of the app through analysis that measures the memory or time complexity, frequency, and duration of function calls, etc. Making your app consistently fast with DMAIC and ReassureĬheck them out later, and now let's jump into the ins and outs of React Native profiling with native tools for iOS and Android.Shipping Fast with Continuous Deployment.The role of Continuous Integration (CI) in improving React Native apps.In other blog posts based on The Ultimate Guide to React Native Optimization, we touch on the following stability-related topics:
Using the right profiling tools allows for spotting the source of performance problems and makes it easier to find a solution that actually makes a difference – and satisfied users mean better business results. That’s why profiling has become one of the main steps in our development life cycle.
With users becoming more sensitive to delays, even a 0.1 sec of improvement can increase your conversion rate by 10.1%. The following article is a part of The Ultimate Guide to React Native Optimization and describes React Native profiling on iOS and Android.
