Tree-sitter based modes do less processing in Lisp (the buffer parsing
is doen by the tree-sitter and the grammar libraries, entirely in C
and C++), so they should in general produce less garbage and require
less GC, yes.
Turning on jit-stealth also lowers the GC pressure because it
fontifies buffers during idle time, so by the time you get to actually
editing a buffer it is already fontified, and thus all the garbage
produced by fontifications was already produced and collected; the
editing itself will produce much less garbage.
Finally, I see that in my customizations I increase gc-cons-threshold
to 1800000 (from the default of 800000), so maybe try that as well.
