You've a good view of this hw. However swap is not important to run
linuxcnc, in fact its to be avoided because it messes with realtime
response. Linuxcnc needs, even with much of the control offloaded to mesa
and similar smart cards, it still needs to check what the machine is doing
1000 times a second. The way I'm doing it, the wobble in this timing as 50
to 80 microseconds, which doesn't bother the machine all that much, the real
time killer is firing up firefox which can lock out the irq response for
hundreds of milliseconds. So I don't carve metal and browse the web at the
same time.
If Firefox is really just for "browsing the web", and is not part of
the user interface for the CNC pieces, I don't understand why you run
Firefox on this machine at all. I would run the browser on a separate
computer, one which isn't so critical to your operation.
