I'm feeling that on my older work desktop too (8 GiB RAM, 2.6 GHz 
quad-core, circa-2010 AMD Deneb). However, I suspect it has mostly to do 
with things other than GC.

The main argument to improve GC is robustness, not typical-case 
performance. We're still installing last-minute hacks into Emacs 26 
because of real-world problems here. It would be useful if we didn't 
have to mess with these hacks because we fixed GC to not blow the C stack.
