[wp-hackers] Caching as part of the core

[Lionel Pointet]

You say you can clear cache with each page saving, but when Otto says 
"page cache", it means a whole HTML page, generated with one post (as 
you mean) and with some other components like nav-menus, sidebars and 
widgets which can access to other contents stored in DB.
So you cannot just think a web page is one post: you said it yourself, 
developers bring some rich components.

Indeed, since it's the developers which bring those components, why 
aren't they considering their cache? Why is it the core's 
responsibility? It just won't work.

And why aren't you happy with the Object Cache API? It is pretty simple, 
useful enough and the default saving (an array in a class) is actually 
good to maintain the number of queries as low as possible on each page 
with a default installation. But if you want, WordPress let you add a 
persistant system over that API (see the object-cache.php drop-in and 
the multiple classes available on the web): you just have to provide 
your class interfacing with that system, and it's already working thanks 
to the API calls done all over the core...
I think choices made are good enough to let user run WP on a lot of 
hosting services, let developers take care of their own caching systems 
easily and keep WordPress as light as possible.

Speaking about 3rp party optimizations like minifying and stuff, WP core 
could take some responsibilities here but I don't think this is a top 
priority since there are plugins doing it already and it's much about 
comfort, not functionality.
