@felixarntz The massive performance benefits you saw in your PR are from this line. At the moment, EVERY time a block template is loaded, it is read into memory. In the case of TT4, this means loading, post meta template for every post on the page. In my test site, around 10 times. This is wasteful.

$template_file is array, with contains theme, slug and path. Making it a good cache key.

@felixarntz This is the most important part of this PR. This caches can never be a be a transient cache. Files can be edited local or by uploading via FTP. This will trigger no cache invalidation.

@spacedmonkey This approach caches more data than my PR #5463, but the concerns that you shared in #5463 (review) apply to this PR as well, as far as I can tell. Can you please clarify what the benefits of this PR are over #5463? |
