If you're powering down the device completely (rather than deep-sleep), you can also swap out the bootloader for something much faster than the ca 130ms the default bootloader takes, but imo it starts getting extremely complicated if you go down that route ( https://github.com/pvvx/Rapid_Loader/ if you're curious; might need to translate from Russian :-)).
