The soon to be released WordPress 6.9 brings several performance enhancements, per The Repository.
I don’t know if they (or any) apply to ClassicPress. (Those for blocks, obviously, don’t.) If so, would it be possible to port the compatible enhancements to CP?
I understand CP is trying to forge its own path/drop the inherence from WP, but it’s hard to pass on performance improvements, no matter where they come from.
Thanks for highlighting this. A little digging reveals that everything is not quite as it seems. Even where these changes might be relevant to CP, any apparent benefit might well be at the cost of increasing TTFB. In other words, less stuff might get loaded but pages would actually load more slowly for the user. So it looks like quite a bit of testing will be needed to work out what, if anything, CP should incorporate of these changes.
Interesting. I’ve been thinking about that, too, regarding some custom optimization I made on my blog, such as preload CSS and preconnect to external domains from where scripts are loaded.
How do you measure the effectiveness of these tricks?
The simplest way is to use the Query Monitor plugin.
