At first app start app that not opened yet start in 4, 5 sec may be in some next updates you will improve it. But it is clear that the performance gain is inversely proportional to battery life. Thanks for your work!
For AOSP Kernel is tested by Pure clean GSI (Generic System Image), if you could try another on another rom, if the issue is solved then its ROM problem by itself. Surely you can contact us in the Telegram support group https://t.me/SpectrumMiatollSupport , we're always glad to help.
