Google har sammanst\u00e4llt resultaten av implementeringen av AutoFDO (Auto-Feedback-Directed Optimization) i Linux-k\u00e4rnbyggen f\u00f6r Android-plattformen. AutoFDO anv\u00e4nder profileringsdata med information om hur ofta olika kodsegment k\u00f6rs f\u00f6r att \u00f6ka prestandan f\u00f6r ofta anv\u00e4nda operationer. AutoFDO-optimering anv\u00e4nds i Linux-k\u00e4rnan 6.12 f\u00f6r Android 16 och 6.6 f\u00f6r Android 15, och kommer \u00e4ven att inkluderas i k\u00e4rnbysget 6.18 f\u00f6r Android 17. Prestandaprofiler f\u00f6r AutoFDO har skapats baserat p\u00e5 k\u00f6rning av 100 popul\u00e4ra applikationer fr\u00e5n C-Suite (Android App Compatibility Test Suite) och simulering av anv\u00e4ndarinteraktioner med dessa applikationer. <\/p>\n

Tidigare har AutoFDO-optimering redan anv\u00e4nts i Android f\u00f6r att bygga systembibliotek och k\u00f6rbara filer i anv\u00e4ndarutrymmet, vilket i genomsnitt har lett till en snabbare programstart med 4 % och en minskning av laddningstiden med 1 %. Fram till nyligen har AutoFDO-optimering dock inte anv\u00e4nts f\u00f6r Linux-k\u00e4rnan, vars komponenter enligt statistik fr\u00e5n Google tar 40 % av processortiden i Android. <\/p>\n

I de genomf\u00f6rda testerna ledde aktiveringen av AutoFDO f\u00f6r k\u00e4rnan till en minskning av laddningstiden med 2,1 %, en snabbare f\u00f6rsta k\u00f6rning av program med 4,3 %, en \u00f6kning av effektiviteten i systemanrop med 9,3 %, en minskning av tiden f\u00f6r mmap-transaktioner Binder med 12,3 %, HwBinder med 20 % och Binder RPC med 21,7 %.
