Comment:

 Hi @bowlerman235,

 `wp_attachment_is()` does make a call to `get_post()` however in the event
 that a WP_Post is passed it'll eventually get passed back. WordPress also
 includes a in-memory cache so that fetching the same post multiple times
 by the same ID will not result in more database queries.

 If you're seeing something other than the above, can you let us know
 exactly what you're seeing?

 This ticket seems `invalid`, however I'll wait for your response before
 closing it for now.
