Yes, that's probably it. Though I'm still surprised by the discrepancy. 
The biggest .el file is not that big. Is Emacs reading all the .el files 
into memory, into a single Emacs instance that buffers all the .el files 
at once?

Oh yes. Even doing the exact same dump twice can yield different 
results, presumably due to ASLR.
