So, do you want to try to increase some gc value in > Emacs master now? No, I think it's too high for being the default (you can, of course, do that locally). Can you instead increase gc-cons-threshold, leaving the percentage at its default value, and see if you can get the same good results? It is much easier for us to bump gc-cons-threshold (assuming the higher value is still reasonable), because that is an absolute number, so it is independent of the heap size.
