Comment (by SergeyBiryukov):

 Replying to [ticket:51691 hellofromTonya]:
 > ''Each time'' `get_template_directory()` runs, ''multiple'' other
 functions and filters also run including these 5 hooks:
 >
 > - `pre_option_template`
 > - `alloptions`
 > - `option_template`
 > - `theme_root`
 > - `template_directory`

 If any of these have specific performance concerns, I think a better way
 forward for this ticket might be to explore adding some object caching or
 static variables to minimize the overhead.

 I think a theme should be able to call `get_template_directory()` multiple
 times without a noticeable performance impact. So I would go with the
 final option here:
 > Another way:
 > - Implement within Core
 >
 > The overall goal is to improve performance by reducing memory, CPU
 cycles, and processing time.
