So it's (/ 91214 64567.0) => 40% more cons-cells
(/ 21758 14423.0) => 50% more symbols
no significant change in markers
(/ 258011 88519.0) => 3x times the string chars.
no significant change in vectors
no change in floats
no significant change in intervals (aka text-properties)
(/ 13174 5376.0) => 2.5 times the strings
It can also be counted as 26K additional cons cells, 7K additional
symbols, 170KB additional string chars, 8K additional strings, for
a total of about:
(+ (* 26000 8) (* 7000 24) 170000 (* 8000 16)) => 650KB
So it ends up increasing Emacs's footprint by a bit less than
a megabyte. It's not the end of the world, but it might be worthwhile
trying to avoid loading this data unless it's really needed.
Of course, maybe there's a way to represent the same info
more compactly or to load it piecemeal (e.g. I've been using a local
hack where C-h v foo-bar RET will try to load foo.el if foo-bar is not
yet defined).
