NVME Samsung 970 EVO too slow

[freshynek]

I use the NVME Samsung 970 EVO SSD as my system disk in Mojave. All benchmarks and System report show correct numbers, but the work is too slow in the real time. I think it is slower than when I use a general SATA SSD.

I have Gigabyte GA-Z370M motherboard with AMD Radeon RX580 graphics card.

What is my problem related to? The clover config? The dedicated GPU sharing the same PCI slot width or something else? My EFI > Clover folder is also attached.

I appreciate any help.

I re-installed Mojave and just after fresh install the numbers were good. But after 2 days and a few installations the speed droped down again. I posted a new thread:

Need help with NVME disk Samsung 970 EVO 250GB MZ-V7E250BW

Right after Mojave 10.14.6 installation, the Black Magic Speed Test shows good results, about 1300 / 3000. After additional installation of Adobe Apps, and some other basic software, the speed drops to 800 / 800. Why? Any help appreciated.

Seems like we are the only men on the planet, having this speed issue with Sams NVMe 970 EVO.

One more here.
Just cloned from a NVME EVO to a Crucial MX and was surprised about the speed increase!!!
Shouldn't be that way, right?
