Comment (by jacobsantos):

 I believe the reason {{{get_post_custom()}}} is that it already uses the
 global ID for the Loop. Using either one will be the same speed, but using
 your method, DD32, will use less memory as all of the metadata will need
 to be copied to the {{{$metadata}}} variable, whereas only the metadata
 that is needed is copied to {{{$encs}}}.

 It is almost a moot point, since both functions pull from the metadata
 cache will get all of the metadata. The copy made in the function will be
 destroyed when the functions go out of scope however, so in the long run
 using {{{get_post_meta()}}} will be more memory efficient.
