This document discusses performance optimization and scalability in CMS systems like Odoo. It covers three main topics: 1. Asset bundles help optimize performance by concatenating and minifying JavaScript and CSS files to reduce page load latency. They are implemented as Odoo views for caching. 2. ORM prefetching allows efficient querying of related records to avoid N+1 queries. It plans parent-child relations in a minimal number of SQL queries. 3. Preforked workers like in Gunicorn help scale the system by handling an increasing workload across multiple processes.
