Easy enough to find out: just run 'top' Here's thje numbers for whay I'm
in front of: Lenovo T440 with 8GB RAM

From top:  7.6 GB RAM,  2.6 GB free, 1.3 GB used (processes)
           3.6 GB file cache
           0.0GB swap used (16.5GB swap space
Processes: 1 process running out of 228

Programs I started: top, Evolution (mail), Brave browser, Pan newsreader.

There's very little difference in terms of memory used when I'm running
a C or Java compilation without unloading any of the rest -  bit less
free memory is all - which probably just means that make, C compiler,
linker and my (written in Java) C documentation generator and all the
source files were still in cache memory from the programming I was doing
before dinner. When I reran a whole library recompile just now it ran
just as quickly as it had earlier, showing that no code or data had been
ejected from cache in the interim.
