Measure before changing
Profile startup, frame rate, memory and the slowest user journeys on representative devices. A clear baseline prevents teams from optimising code that is not responsible for the visible problem.
Control rendering work
Keep component boundaries clear, avoid unnecessary updates and use list virtualization deliberately. Large images, complex animation and unbounded state can create more pressure than the framework itself.
Improve data and navigation
Cache responsibly, avoid serial request chains and move expensive work away from the first useful screen. Navigation should feel immediate even when secondary data continues loading.
Make performance continuous
Add release monitoring, budgets and regression checks to the delivery process. Device-level traces and real-user evidence should inform every significant framework or dependency upgrade.
