Comment (by ivailohristov):

 It seems like the main performance benefit here comes from having the
 theme content grouped into a single object. I did a quick and dirty test
 of the same logic but instead of using transients in the DB the object is
 now saved as a simple file in the system's temp directory. In my tests
 this performs even better than the current transient based implementation.
 Do you think it is worth considering a file based implementation for this
 instead of putting further stress to the DB?

 Please take a look here: [https://github.com/felixarntz/wordpress-
 develop/compare/performance/theme-template-file-contents...ivailohristov
 :wordpress-develop:performance/theme-template-file-contents-cache]

 Furthermore this implementation gets rid of the need for timeouts and
 development mode. Theme changes are reflected immediately.

 Here is how the averages for loading template paths look on my end (over
 100 requests) when using transients vs file cache:

 transients: 0.00062347412109375s
 file cache: 0.00031973838806152s
