Connection Pool Performance Analysis

Analyze PHP code for connection pool issues and database connection management problems.

When to Use

• Reviewing database-heavy PHP applications
• Investigating connection exhaustion or memory leaks
• Auditing long-running workers (queue consumers, daemons)
• Checking Doctrine EntityManager lifecycle issues
• Reviewing HTTP client usage patterns

Analysis Approach

1. Scan for connection creation patterns (PDO, Redis, Guzzle)
2. Check loop bodies for repeated connection instantiation
3. Verify try/finally cleanup on pool acquire/release
4. Check timeout configuration on all connection types
5. Review persistent connection usage and state reset
