Backend Performance Tuning

Frontend optimisation is limited by your server response time. We profile and tune backend performance — API latency, TTFB, database query performance, and throughput — ensuring your frontend optimisations are not bottlenecked by slow servers.

// Key benefits

What makes this service valuable

Profiling-driven changes

We profile your application under realistic load before changing a line of code — identifying actual bottlenecks rather than optimising what appears slow intuitively.

Database query optimisation

N+1 queries, missing indexes, lock contention, and connection pool exhaustion are common culprits. We diagnose and resolve the database performance issues causing the largest latency improvements.

Throughput and concurrency

Connection pooling, async processing, queue architecture, and horizontal scaling configurations that maximise throughput under concurrent load.

Server response times that do not limit your frontend

Backend performance profiling surfaces the 20% of code responsible for 80% of latency. Premature optimisation wastes time; profiling-driven optimisation targets the exact bottlenecks with measurable impact.

We use APM tools (Datadog, New Relic, Pyroscope) and database query analysis (pg_stat_statements, EXPLAIN ANALYZE) to build a complete picture before implementing changes.

// What this includes

  • APM-based latency profiling
  • Database query analysis (EXPLAIN ANALYZE)
  • N+1 query identification and resolution
  • Index analysis and implementation
  • Connection pool configuration
  • Caching strategy implementation
  • Load testing and throughput measurement

Common questions about backend performance tuning

What is a realistic target for API response time?+

P50 under 100ms and P99 under 500ms are reasonable targets for most API operations. Read-heavy endpoints with proper caching can achieve P50 under 20ms. Write-heavy endpoints with database operations typically target P50 under 200ms.
