Comment (by thekt12):

 I have got some initial performance improvement metrics for `file_exists`
 caching only (I didn't cache the template from `locate_block_template` due
 to the complexity explained in the previous comment ).

 There is a minimal ( just 2 to 3 ms ) but a consistent improvement from a
 cached `file_exists` over a non-cached one.

 Some initial numbers are documented in the PR for reference -
