Don't let this gap widen
Without expert mastery of Doctrine ORM, PHP teams lose 45% of their time on unoptimized queries, driving 30% higher database costs in production.
N+1 query incidents cause 60% of application slowdowns, with a 25% failure rate on critical deployments according to Stack Overflow 2025.
