I recommend running the command at the same time as you have some load on the CPU, it gives the best result in my experience. So run the command while at the same time processing a few FGRP tasks ideally. There is a discussion about this in the same thread I think - if in doubt you can try it out yourself, just create several wisdom.dat files and see which one is best.
When I run this command it goes away and doesn't come back until I do a control C?

DON'T CTRL-C the terminal session. Just let it run. It can take up to 30 minutes before finishing the profile depending on the speed of your cpu. Once the profile is finished, the terminal prompt will appear and you can close the terminal session and you can find your new wisdom file in the project directory.
Apparently Linux Gamma-Ray#5 cpu tasks have the following results on two different Amd model cpus.
Neither run with Turbo settings.
Amd 2700 ~8 hours
Amd 3950x ~3 hours
The Ryzen 3950X is Zen 2 based silicon with much greater FPU performance over the older Ryzen 2700X Zen+ architecture. Really night and day difference in the designs. That is primarily the difference in observed results.
Why is this not done by the project automatically?
Because your pc needs to stop crunching and be disconnected from the net etc to get the best results, how does an online program do that? Follow the links in the early part of the discussion and you will see how it's done.

The app could hog all available threads and prevent other projects from crunching. Disconnecting was mentioned as a recommendation.
Be it as it may, it sounds like a headache. I guess having dedicated users take care of it themselves is good decision.
I actually ran the first wisdom profile while I was crunching. Didn't seem to have any effect. No different than running with BOINC stopped on another host. But I am crunching on either 24 or 32 thread cpus.
Depends on whether the science app is written to run the profiler first whenever a wisdom file is not found.
The old BRP4G gpu app for Windows did this. But I guess the developers didn't bother to write that function into the FGRP5 cpu application.

Mine only took about 10-15 minutes to generate the file. But I'm sure I run my cpus much faster than you do at stock.

Wasn't any headache at all. Just a quick copy and paste in Terminal and wait 10 minutes. Done.
