Lock contention affects overall database performance

Lock contention impacts overall database performance, with the extent varying based on overall database traffic levels. Higher traffic amplifies the performance impact of locking issues.

Use pg_locks system table to monitor lock contention over time and correlate with traffic patterns. Review Section 54.12 for pg_locks view details and Chapter 13 for concurrency management strategies. Analyze which lock types and relations contribute most to contention during peak traffic periods.
