Performance Optimisation
"Find exactly where time and resources are wasted — then fix it"
Slow applications cost revenue, frustrate users, and quietly erode confidence in your platform. We find exactly where time and resources are being wasted — then eliminate those bottlenecks with targeted, measurable improvements.
When to call us
Climbing response times
Page load or API response times rise as user numbers grow.
Cloud bills outpacing growth
Infrastructure costs are growing faster than your user base.
Conversion drops without cause
Conversion or retention metrics drop without an obvious reason.
Peaks break the system
The system struggles or degrades under promotional events or month-end runs.
Seconds-long DB queries
Database queries take seconds rather than milliseconds.
High idle CPU/memory
CPU or memory usage stays high without a workload to explain it.
Six optimisation surfaces
APM & profiling
Deep instrumentation with distributed tracing to pinpoint the exact lines of code consuming the most time.
Database tuning
Query analysis, index optimisation, schema refactoring, and connection pool right-sizing.
Load & stress testing
Realistic traffic simulations that expose breaking points before your users find them in production.
Caching strategy
CDN configuration, in-memory caching layers, and cache invalidation patterns that cut origin load dramatically.
Frontend performance
Bundle analysis, lazy loading, Core Web Vitals improvements, and render-blocking resource elimination.
Infrastructure right-sizing
Matching compute, memory, and network resources to actual workload patterns — reducing waste without sacrificing headroom.
Measured improvements, not speculative rewrites
Baseline & instrumentation
Instrument the application with APM to capture real latency, throughput, and error rate data under genuine load.
Bottleneck analysis
Flame graphs, distributed traces, slow query logs, and infrastructure metrics analysed together — bottlenecks ranked by impact/effort.
Targeted remediation
Fixes implemented incrementally — each change tested in isolation so we know precisely which improvement drove which gain.
Load testing & validation
Realistic load scenarios — including projected peak traffic — confirm the application performs to target before changes reach production.
Layers we instrument
Frontend & CDN
Core Web Vitals, asset delivery, render-blocking resources, and edge caching configuration.
Application layer
Hot code paths, memory leaks, thread contention, serialisation overhead, and N+1 query patterns.
Data layer
Slow queries, missing indexes, lock contention, replication lag, and inefficient ORM usage.
Network & infrastructure
Latency between services, DNS resolution time, connection pooling, and resource over-provisioning.
