Optimization - Making your app faster
summary
Grab mobile apps use app slicing and asset catalogs to cut download size (Apple claims ~65% savings) and turn on on-demand resources via target resource tags to avoid shipping bulky game assets. Reduce data with gzip, inspect headers with Charles, and test slow links with the network link conditioner. Measure latency (example: 63 ms vs 890 ms server first-byte delays) and batch close-timed requests to save radio power; consider protobuf (~6% smaller) only after other optimizations.
