What is really difficult to collect is whether the cancellation signal can pass through the Task, bridging layer and side effect boundaries, and do not let the old results be fed back on the page

The biggest fear when starting optimization is not distinguishing which tasks belong to the critical path and which ones are just thrown in.

The real trouble with picture problems is that downloading, decoding, scaling, memory usage and display timing are all intertwined.

List lagging is usually caused by the main thread taking on too much work that competes with the current frame during the scrolling process.

Locating the problem type first, and then deciding on tools and analysis paths is more effective than starting full troubleshooting.

What really needs to be optimized are specific issues such as startup, lagging, memory, and power consumption that will directly affect user experience and engineering costs.
