Framework-Native Performance

Doctrine query analysis: eliminate N+1, optimise DQL, apply query caching
Cache pool strategies: Redis, APCu, filesystem, chain adapters with intelligent invalidation
Container compilation: preload, service optimisation, parameter resolution
HTTP caching: Symfony HttpCache, Varnish integration, ESI fragments
Profiler-guided optimisation: identify bottlenecks with Symfony Profiler and Blackfire
Code-level improvements: reduce service instantiation, optimise event listeners
N+1 query problems cause 10-100x slowdown in production applications when development teams don't recognise inefficient Doctrine queries early. We implement eager loading via DQL fetch joins to eliminate these performance killers, apply query result caching through Doctrine's result cache layer, and configure second-level distributed query caching for frequently accessed data. Our systematic approach to Doctrine optimisation typically achieves 80%+ query reduction whilst maintaining data integrity and application functionality across all environments.

Our Performance Methodology

Framework expertise meets production reality

Profiler Analysis

Use Symfony Profiler, Blackfire, and custom instrumentation to identify slow database queries, inefficient service instantiation, and memory leaks. We measure everything before optimising.

Doctrine Tuning

Eliminate N+1 queries with fetch joins, implement result caching, optimise DQL queries, apply second-level cache. Doctrine performance requires framework-specific expertise.

Cache Pool Configuration

Configure Redis for session and cache storage, implement chain adapters for multi-tier caching, optimise cache invalidation strategies. Proper cache configuration is critical for Symfony speed.

Container Compilation

Preload PHP opcache with compiled containers, optimise service instantiation, reduce autowiring overhead, implement lazy services. Container performance impacts every request.

HTTP Caching

Implement Symfony HttpCache or Varnish integration, configure ESI fragments for dynamic content, set intelligent cache headers. Edge caching dramatically reduces backend load.

Code Optimisation

Reduce service dependencies, optimise event listener priority, implement lazy loading, refactor inefficient business logic. Clean code is fast code.

Performance Delivers Business Value

Faster applications mean better user experiences and lower costs

Higher Throughput

5x throughput
Optimised Symfony applications handle 5x more concurrent requests with the same infrastructure. Serve more customers without scaling servers.

Sub-100ms Responses

< 100ms response
Properly tuned Symfony delivers sub-100ms API responses. Users experience instant feedback, improving engagement and satisfaction.

Reduced Database Load

-80% queries
Doctrine optimisation and intelligent caching reduce database queries by 80%+. Reduced database load typically decreases infrastructure costs.

Lower Infrastructure Costs

-50% hosting costs
Efficient code and caching mean fewer servers required. We regularly help clients reduce hosting costs by 50% while improving performance.
