I don't know which kind of experiment you have applied, so I cannot say
anything about the compilation errors. However, I wonder where paths
like "net/tramp-loaddefs.elc" come from. We're speaking about
package.el, meaning we're speaking about ELPA. Tramp in ELPA doesn't use
any subdirectory "net".

Anyway, I don't believe we'll see a performance boost after
byte-compiling loaddef files. They just contain function and variable
declarations, no implementation (but the initial values of variables).

There are exceptions like in tramp-loaddefs.el, but they still don't
count wrt performance, I believe.

Best regards, Michael.
