I think the reason, as Uwe already said, is that you have to load
the lazyload index file, and in your case that file is likely to
be as large as the R file itself.

If these are all very small functions, lazy load won't be of that
advantage, because you have to load the index file anyway.
You know, R including all base and recommended packages has just ~ 6Mb of R
code. Are you really sure
