MP 1,1-5,1 Slower performance after open core install

[George Deley]

Hi all having a bit of an issue.

I installed opencore on my 3,1. On to a raid 10 configuration and ever since my Mac has slowed down so much that it’s honestly annoying to use.

I have done a time machine restore removed efi folder. Better but still not great.

so resulted in wiping all disk deleting raid and rebuilding off adosdude Mojave installer(usb drive)! Which Also slow?

hopfully after the rebuild, fresh install of Mojave I might be closer but I was wondering if anyone could shed any light on this situation?

also my write speed has dropped by 400mb

read speed dropped a bit

Also done a nvram reset but only once with all drives in

Have you checked the drives health with a smart tool like drivedx?

no I haven’t yet! Going to have to wait until Mojave installs now until I can do anything like that? Everything’s just so slow it’s annoying

Get an usb thumb drive with at least 32 GB and install high sierra 10.13.6 on it.

It is a nice test tool and you can run diagnosis from.

It is also slow but usable for tests.
