Thanks - I moved the old CentOS stuff - off to an old machine - this is
SATA disk...
The new 22.04 LTS runs just fine now on nvme PCi4.0

System speed is just fine now.
However I am surprised that my "appearance" of disk speed like compile time
is not faster.
My system has 128G ram, i9-7960x and its basically the same compile speed
as the old SATA. I thought it would be faster with the faster nvme.
This is not just one program - there are 190 files... make -j 8 kind of
stuff, and basically same speed as the OLD sata.
I am even using ccache.

is there something I need to tweek?
Thanks,

Jerry
