Has it?  I haven't noticed any substantial slow-down...  (Unless you
mean with native-comp switched on.)

In any case, autoload generation takes a substantial chunk of time --
especially since it's single-threaded.  Glenn's suggestion to copy over
ldefs-boot.el (if it's newer) sounds like a good idea to me.  (And I'd
also like if that file was regenerated more often than once a month...)
