Grav 2.2 cuts cold starts and memory use on large sites

Grav 2.2.0 changes page-cache rebuilding so it no longer writes and compiles one PHP file per page, cutting reported cold-start times by about half in tests with 1,081 and 10,321 pages.

On the 10,000-page test site, back-to-back warm requests fell from 69.9 ms to 18.2 ms, while the lazy page index, now automatic for sites with 1,000 pages or more, reduced reported memory use by 96%.

Admin page saves now mark pages as changed instead of clearing the entire cache, reducing the reported next-page-view time after a save from 1,075 ms to 67.9 ms on the 1,000-page site.
