# leanPerformance

fun [leanPerformance](https://docs.maptiler.com/mobile-sdk/android/api/-map-tiler-s-d-k/com.maptiler.maptilersdk.helpers/-m-t-performance-presets/lean-performance/)(base: [MTMapOptions](https://docs.maptiler.com/mobile-sdk/android/api/-map-tiler-s-d-k/com.maptiler.maptilersdk.map/-m-t-map-options/) = MTMapOptions()): [MTMapOptions](https://docs.maptiler.com/mobile-sdk/android/api/-map-tiler-s-d-k/com.maptiler.maptilersdk.map/-m-t-map-options/)

Lean performance preset: prioritize responsiveness and bytes over fidelity.

Applied overrides (favor performance over fidelity):

-   pixelRatio = 1.0
    
-   shouldRefreshExpiredTiles = false
    
-   cancelPendingTileRequestsWhileZooming = true
    
-   maxTileCacheZoomLevels = 4.0 (if unset)
    
-   crossSourceCollisionsAreEnabled = false
    
-   eventLevel = ESSENTIAL (keeps low-frequency events; per-frame events opt-in)
    
-   highFrequencyEventThrottleMs = 150 (when ALL is enabled)
