In Android 11, google introduced IORap, a new feature which greatly improves application startup times.

IORap prefetching for Android apps<\/strong><\/p>\n\n\n\n

IORap reduces app startup times by predicting which I\/O will be required and doing it ahead of time. Many app startups have a lot of time that the IO request queue isn\u2019t being saturated because of blocking I\/O. As a result, we aren\u2019t maximizing IO latency. After prefetching the data and compacting the I\/O, the app can access this data nearly instantly from the pagecache<\/code> , significantly reducing app startup latency.
\"\"<\/p>\n\n\n\n

When they evaluated some popular top apps from the Play Store, 80%+ spent 10%+ time in blocking I\/O during launch time. while ~50% of the apps even spent 20%+ time. A majority of apps they looked at could benefit from IORap.
