I understand. And that's a good approach. As you know, you can also use
`eval-after-load' to avoid doing some stuff unnecessarily.
As with any performance problem, start by attacking the biggest hogs. It sounds
like your 50 Org-mode agenda files constitute 2/3 of your performance problem at
the moment, so perhaps start there.
Do you really need to load all of your Org agenda files? Do they need to be so
big/slow? Does Org mode provide any constructs that might alleviate some of
this penalty?
I don't have answers for you, sorry. Except for this obvious one: try starting
Emacs less often and keeping your Emacs sessions open longer.
Oh, and of course byte-compile the code you load. (You mention whitespace lines
and commented lines, but those are irrelevant for byte-compiled code.)
And maybe try profiling code for the worst parts of your problem. Perhaps
you've hit a bug or two, or perhaps you've found an opportunity for some library
to be improved wrt load performance.
