The upcoming ‘Interpreted mode’ option allows disabling the AOT/JIT compiler. This can significantly speed up app installation on Android 5.0 and 6.0.
I tested this on a low-end device where the installation time of Telegram was improved from 30 seconds down to 10 seconds.
Of course, this comes at the expense of runtime performance so this should only be used when testing different cloning options.
No point using this option on Android 7.0 as it no longer performs full AOT compilation during the installation process.
