Performance Audit | Latency & Scaling

Slow applications cost revenue, users, and nerves. Every second of load time can reduce conversions by 7%. A performance audit identifies bottlenecks systematically – from frontend to database – and delivers prioritized actions with measurable impact.

What We Review

Frontend & Core Web Vitals

LCP, INP, CLS, render path, bundle size, critical CSS

Backend Profiling

Timeouts, queueing, N+1 queries, async processing, memory leaks

Database Analysis

Indexes, access paths, locks, IO/CPU budget, connection pooling

Caching & Infrastructure

CDN, edge strategies, Redis/Memcached, browser caching

Typical Quick Wins from Our Audits

Missing database indexes → 10x faster queries

N+1 query patterns → 90% fewer DB calls

Unoptimized images → 50% smaller payloads

Missing HTTP caching → 80% cache hit rate

Blocking JavaScript → 2s faster LCP

Inefficient serialization → 40% less CPU

Connection pool tuning → stable response times

CDN configuration → 200ms less latency

Why Performance Optimization Is Business-Critical

Slow applications don't just cause user frustration – they directly impact your business success. Studies show that even a 100-millisecond delay can reduce conversion rates by up to 7 percent. For e-commerce companies, this means concrete revenue losses in the five- to six-figure range per year. Even with internal business applications, every second of wait time costs real money – through lost productivity and rising infrastructure costs.

A professional performance audit addresses exactly this: instead of generically upgrading hardware or scaling up cloud resources, we identify the actual bottlenecks in your stack – from inefficient database queries to missing caching strategies to suboptimal frontend architectures. The result is targeted measures that not only improve performance but simultaneously reduce your infrastructure costs and sustainably increase user satisfaction.

Your Result

You receive a prioritized action list with impact/effort ratings. Quick wins like query optimization or caching adjustments can often be implemented right away. Plus a roadmap for sustainable scaling – including measurement points for success validation.

Typical duration: 1-3 weeks

Deliverable: Performance report + roadmap

Frequently Asked Questions About Performance Audits

When is a performance audit worthwhile?

A performance audit is worthwhile when: load times exceed 3 seconds, timeouts occur under load, infrastructure costs rise without growth, traffic peaks are planned (campaigns, seasonal business), or before a relaunch. Even preventively, an audit is valuable to identify scaling limits early.

What does a performance audit cost?

A focused audit (e.g., frontend only or database only) costs EUR 5,000-10,000. A full-stack audit including backend, DB, frontend, and infrastructure costs EUR 15,000-25,000. The price depends on system complexity and the desired depth of analysis.

Do I need load tests in addition to the audit?

Load tests and audits complement each other: the audit identifies optimization potentials through code and architecture analysis. Load tests validate the improvements and determine scaling limits under realistic conditions. We offer both and recommend the combination.

How quickly will I see improvements?

Quick wins like index optimizations, caching adjustments, or query fixes often take effect within days. Structural measures like architecture refactoring take weeks to months. In the audit, we prioritize by impact/effort ratio so you see initial successes quickly.

Can you also help with cloud costs?

Yes, performance optimization and cost optimization often go hand in hand. More efficient code requires fewer resources. We also analyze your cloud architecture for over-provisioning, suboptimal instance types, and missing auto-scaling strategies.
