PostgreSQL Performance Tuning & Query Optimization
A slow PostgreSQL database can impact your entire application — from delayed queries and high CPU usage to replication lag and unhappy end-users. Performance problems often come from inefficient queries, missing indexes, table bloat, poor schema design, or misconfigured PostgreSQL parameters.
At Mafiree, we specialize in PostgreSQL performance tuning and query optimization to help businesses unlock the full power of their database. Our experts analyze query execution plans, server configuration, indexing strategies, partitioning, and connection pooling to deliver a faster, more scalable, and more reliable PostgreSQL environment
Why Choose Mafiree for PostgreSQL Performance Tuning?
- Hands-on experience with large-scale, high-transaction PostgreSQL workloads
- Deep expertise in execution plans, indexing strategies, and partitioning
- Proven methods to reduce query latency, CPU load, and storage bloat
- Expertise in autovacuum tuning, memory allocation, and I/O optimization
- Practical fixes that balance performance, stability, and cost efficiency
Our PostgreSQL Performance Tuning Services
Query Optimization
- Detailed review of query execution plans (EXPLAIN/ANALYZE)
- Index tuning, covering indexes, partial indexes, BRIN indexes for large datasets
- Query rewriting for complex joins, aggregates, and subqueries
Server Configuration Tuning
- Optimize key parameters: shared_buffers, work_mem, maintenance_work_mem, effective_cache_size
- Autovacuum tuning to control table bloat and maintain performance
- Connection pooling optimization with PgBouncer or Pgpool-II
Schema & Index Design
- Optimize schema for normalization vs. denormalization trade-offs
- Partitioning strategies (list, range, hash, or pg_partman automation)
- Advanced indexing techniques to cut down query time
Workload & Resource Optimization
- Identify bottlenecks in CPU, memory, and I/O utilization
- Optimize replication performance for read scaling
- Performance tuning for analytics workloads, time-series (TimescaleDB), and geospatial (PostGIS)
Continuous Monitoring & Health Checks
- Ongoing monitoring for slow queries and blocking locks
- Performance dashboards and query alerting
- Proactive recommendations for long-term stability
Common PostgreSQL Performance Issues We Solve
- Slow queries and full table scans
- Replication lag due to poorly tuned parameters
