Re: emacs empty startup time increased from v 27.1 to 29.0 by factor 3?

[John Yates]

I work on a product whose structure involves literally hundreds of
DLLs / SOs.  We tolerate slow start-up in-house because it optimizes
the compile / edit / debug cycle.

Packaging the final product involves an extra step to collapse our
hundreds of images into just a handful via a secondary link step.
I wonder if there is anything analogous that Emacs could do.
