While I never profiled its effects, I have mitigations off on all of my DC-dedicated computers.
It was a small nuisance to figure out how to set the GRUB config accordingly in Mint.
In OpenSuse, there is a dialogue for this in their central system management GUI.
I ran your llrDIV script on my 2P Ivy with mitigations on and off and although the trend seemed to be a slight improvement, I doubt it's statistically significant.
Mitigations on:
Correct. You can enter as many kernel parameters as you need, separated by space characters, and in any order.

Every percent counts. ;-)
Perhaps GPGPU workloads profit more, as they involve more calls into the kernel, and device I/O.

In drag racing they call this "stacking tenths," referring to arriving just a tenth of a second faster at the finish. One small change may not seem to make a difference, but many small changes do.
I shut down the 2P Ivy beast for now. The PPD is between a 3700X and a 3900X and it draws 310 watts from the wall with turbo boost off. I'll replace it when you can actually buy hardware sometime in the future.
