Half a second is actually quite a big deal.

"A delay of less than 100 milliseconds feels instant to a user, but a delay between 100 and 300 milliseconds is perceptible. A delay between 300 and 1,000 milliseconds makes the user feel like a machine is working, but if the delay is above 1,000 milliseconds, your user will likely start to mentally context-switch."

Not in the context of an 8 second boot time. Almost no one will notice 8 vs 8.5s

Most apps start in about a second.
