Title: Reduce boot time [Print This Page] Author: LEDgris2 Time: 8/21/2021 21:45 Title: Reduce boot time Hi
I'm trying to reduce the boot time. From the boot log it seems that something in the initramfs might take ~3s? Is it the mounting of root fs?
Do you have any advice to reduce the time in boot between [ 2.100622] and [ 4.987011]?

A buddy mentioned he had fun playing online and I wanted to see what he meant. That’s how I ended up at spin mama casino, where I tested out roulette for the first time in ages. Watching the ball roll kept me on edge, and after a few misses I finally hit a winning bet. That small success gave me a real rush. It turned out to be way more engaging than I thought it would be.Author: joefox656 Time: 3 day before
