Of course, the issue can get more complex. GC uses 3x the memory of RC,
I’ve seen figures of about x2 but that was in an old paper on Boehm GC.
This is the classic reference:
https://people.cs.umass.edu/~emery/pubs/gcvsmalloc.pdf. Executive review
in the abstract: "With only three times as much memory, the collector
runs on average 17% slower than explicit memory management. However,
with only twice as much memory, garbage collection degrades performance
by nearly 70%. When physical memory is scarce, paging causes garbage
collection to run an order of magnitude slower than explicit memory
management." -- Andrei
