Compose Multiplatform benchmarks

Run Desktop

• ./gradlew :benchmarks:run

Run native on iOS

Open the project in Fleet or Android Studio with KMM plugin installed and choose iosApp run configuration. Make sure that you build the app in Release configuration. Alternatively you may open iosApp/iosApp project in XCode and run the app from there.

Run native on MacOS

• ./gradlew :benchmarks:runReleaseExecutableMacosArm64 (Works on Arm64 processors)
• ./gradlew :benchmarks:runReleaseExecutableMacosX64 (Works on Intel processors)

Run K/Wasm target in D8:

./gradlew :benchmarks:wasmJsD8ProductionRun

or with arguments:

./gradlew :benchmarks:wasmJsD8ProductionRun -PrunArguments=benchmarks=AnimatedVisibility

To build and run a K/Wasm D8 distribution for Jetstream3-like:

./gradlew :benchmarks:buildD8Distribution --rerun-tasks

then in a distribution directory run using your D8 binary:

~/.gradle/d8/v8-mac-arm64-rel-11.9.85/d8 --module launcher_jetstream3.mjs -- AnimatedVisibility 1000

Run in web browser:

Please run your browser with manual GC enabled before running the benchmark, like for Google Chrome:

open -a Google\ Chrome --args --js-flags="--expose-gc"

• ./gradlew clean :benchmarks:wasmJsBrowserProductionRun (you can see the results printed on the page itself)

Benchmarks description

Benchmark Name	File Path	Description
AnimatedVisibility	benchmarks/src/commonMain/kotlin/benchmarks/animation/AnimatedVisibility.kt	Tests the performance of the AnimatedVisibility component by repeatedly toggling the visibility of a PNG image.
LazyGrid	benchmarks/src/commonMain/kotlin/benchmarks/lazygrid/LazyGrid.kt	Tests the performance of the LazyVerticalGrid component with 12,000 items and jumps to specific items multiple times while running.
LazyGrid-ItemLaunchedEffect	benchmarks/src/commonMain/kotlin/benchmarks/lazygrid/LazyGrid.kt	Same as LazyGrid but adds a LaunchedEffect in each grid item that simulates an async task.
LazyGrid-SmoothScroll	benchmarks/src/commonMain/kotlin/benchmarks/lazygrid/LazyGrid.kt	Same as LazyGrid but uses smooth scrolling instead of jumping to items.
LazyGrid-SmoothScroll-ItemLaunchedEffect	benchmarks/src/commonMain/kotlin/benchmarks/lazygrid/LazyGrid.kt	Combines smooth scrolling with LaunchedEffect in each item.
VisualEffects	benchmarks/src/commonMain/kotlin/benchmarks/visualeffects/HappyNY.kt	Tests the performance of complex animations and visual effects including snow flakes, stars, and rocket particles.
LazyList	benchmarks/src/commonMain/kotlin/benchmarks/complexlazylist/components/MainUI.kt	Tests the performance of a complex LazyColumn implementation with features like pull-to-refresh, loading more items, and continuous scrolling.
MultipleComponents	benchmarks/src/commonMain/kotlin/benchmarks/example1/Example1.kt	Tests the performance of a comprehensive UI that showcases various Compose components including layouts, animations, and styled text.
MultipleComponents-NoVectorGraphics	benchmarks/src/commonMain/kotlin/benchmarks/example1/Example1.kt	Same as MultipleComponents but skips the Composables with vector graphics rendering.
