Hello!
FreeBSD provides a mechanism to load CPU microcode. Is there any good reason to do that?
I have tried
and also installed the port: devcpu-data
Everything works. Also, running the single core integer and pointer performance test after the microcode upgrade shows 0.1% (yes 0.1 per cent) decline in performance.
Another, more sophisticated GPU test (glmark2) gives me (hudge) 31.8% performance decline after microcode upgrade.
My question here is - is there any good reason to make the CPU microcode upgrade permanent during boot?
