Hi Marcus,
Saw your issue with slow query execution and CPU spikes under peak database traffic. I specialize in PostgreSQL performance tuning.
Immediate steps:
1. Run EXPLAIN (ANALYZE, BUFFERS) to isolate sequential scans.
2. Implement covering indexes and partial indexes on frequently filtered status columns.
3. Tune connection pooling with PgBouncer to eliminate connection churn.
Happy to inspect your slow query log today.
Best,
Alex
