Your CakePHP Index Page Is Running 101 Queries. contain() Fixes That.
CakePHP loads associations lazily, so a simple article list can fire one query per row. Here's how contain() fixes the N+1 problem, how to verify it, and when eager loading goes too far.
cakephpHibernate Pagination: setFirstResult/setMaxResults, the Fetch-Join Trap, and When to Switch to Keyset
Hibernate's setFirstResult/setMaxResults paginate in the database — until a collection fetch join silently moves pagination into JVM memory. Here's how to spot it, fix it with a two-step query, and when to switch to keyset pagination.
