MP 1,1-5,1 Boot too slow with opencore and nvme

[yukdave]

My Open core boot time from SSD was 2 minute total while my NVME boots are almost 5 minutes. I have 1qty NVME for Boot and 1qty NVME for data drive. I took my older pair of SSD and kept them as super duper backups. I reinstalled OS Mojave on the NVME boot drive to get back the Recovery Partition and that cleaned up some stuff. I did the same to the backup Boot SSD clone of boot. So yeah open core slows boot down a bunch.

My boot time is 15 seconds (7 to chime and 8 until the apple progress bar). I think this is due to my loading my 3 kext files straight from the system instead of through OpenCore and having 24GB of ram. Some say it's safer to load kexts through OpenCore. I disagree. It was safe before everyone got on the OpenCore kick. Anyway, I think the less that has to be read from the config.plist will make an improvement.

Take a second, divide it by 20 and reduce that time by a bit.
What's left is how long it takes OpenCore to inject a kext.

I.e., the difference between 8 and 40+ seconds from chime to screen is not down to kexts.

I'm always surprised by people incessantly trying to improve Mac Pro boot times since I almost never shutdown my Mac Pro, only when we have electric storms/power problems or to clean it/install something. Even if takes three or four minutes to boot, won't matter for me at all.

On the other hand, I don't tolerate sleep problems and I tested and changed a lot of cards until I got a config that have working sleep.

I said I think that may be the reason. Either way, I'm happy with it at 15 seconds or two minutes as long as it works. Besides, even having the exact same model won't stop the difference that will occur between the two. I guess I'm just one of the lucky few.

You give me an excellent idea, sleep instead to shutdown every time, I guess that it's almost the same thing, and with time, I'll no have problems with my mac pro.

how is open core running Mojave? I want to run that before I start with the Catalina upgrade. I am still on Mojave since it is stable and supported with security upgrades. Do I have to do a different setup for open core?

the best thing is when the computer wakes up at night and all the drives start to take off like the Millennium Falcon from Star Wars

If you have the option checked to wake for network access, you will experience the Star Wars event. I don't want my Mac to wake-up every hour from sleep, just to check email.
