Performance

Cuts the sequential Redis round trips a Drupal request makes, for sites whose cache is a network hop away: cross-AZ ElastiCache, a managed Redis, any topology where a cache read costs milliseconds.

Performance tuned clones of the core database drivers for MySQL, MariaDB, PostgreSQL and SQLite. Keeps the database connection open between requests. Pages load up to 63% faster on PostgreSQL.

Agent Surface exposes what your site publishes to anonymous visitors in the format machine consumers prefer, and declares in machine-readable form how that content may be used.

INTRODUCTION

Downloads external JavaScript and CSS CDN assets declared in libraries.yml into Drupal’s libraries folder, rewrites library definitions to use the local copies, and reports status.

Makes the live runtime requirements check on the Configuration page optional, so one slow module no longer makes /admin/config slow for every administrator. The status report is unaffected.
