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.
