WordPress Performance Trac tickets @westonruter shared that prefetching has finally been committed in changeset 64120. The next step is to default script and style concatenation to off outside development environments in PR #13090. After that, the plan is to remove load-scripts.php and load-styles.php, along with the concatenation and compression logic that has been problematic for many years. Open Floor @westonruter noted performance gains in PHPStan 2.3.0: a full uncached analysis of WordPress core went from 60 seconds to 8 seconds. He shared the PHPStan 2.3.0 release post.
