What can I do outside of KSP to reduce garbage collection stutters?

What, if anything, can I do with my hardware, PC settings, etc to reduce garbage collection stutters?

Not really.

Faster memory and CPU will reduce the -length- of the stutters (as they complete faster), but if you have anywhere near modern hardware there is not much improvement that can be had.

More memory will only help if you are memory starved ( < 8gb), and even then it can only delay the onset of the stutters, and only when combined with something that increases the Unity heap size (see below)  (without the heap-size increase, KSP won't use the additional memory unless it 'needs' it for new allocations)

The only 'fix' that I'm aware of is to use MemGraph(?) and up the heap size.  This doesn't solve the problem, but it will reduce the frequency of the pauses (but can also make them longer when they do occur, as there is more stuff in memory to look over for GC).
