Slow Systems Cost Real Money

We embed performance as a continuous engineering discipline — not a one-time test before go-live — delivering measurable SLA confidence, capacity assurance, and revenue protection at every stage of your delivery pipeline.


What's at Risk Without It
£2M+
revenue lost per day for a major UK bank during a payment platform outage due to load-triggered failures at peak — preventable with capacity planning
7%
conversion drop per 1-second latency increase — on a £100M revenue e-commerce site, this is £7M annually
4%
annual revenue loss attributed to performance issues on websites, per CISQ 2024 analysis
20–40%
Cloud over-provisioning without capacity engineering adds unnecessary infrastructure cost — we eliminate waste while ensuring headroom
What We Deliver

CoE Consultation and Advisory

We establish your performance NFRs from business goals — not guesswork. SLA, SLO, and SLI definitions aligned to revenue targets and customer experience benchmarks.

Performance Engineering

Performance tests embedded in every sprint and CI/CD pipeline — catching regressions at code commit, not at go-live. Up to 60% fewer performance defects reaching production.

CX and Digital Performance

Deep-dive performance engineering for complex, multi-tier enterprise systems — ERP, CRM, core banking, insurance platforms — where architectural bottlenecks are often hidden from surface-level testing.

Cloud Engineering & Optimisation

Validate auto-scaling, elasticity, and cloud-native performance under realistic production conditions. Identify region-specific latency, cold-start issues, and cloud configuration gaps before they cost you.

AI and Agentic Performance

Data-driven forecasting of infrastructure needs for planned growth, seasonal peaks, and demand spikes. Eliminate over-provisioning waste and ensure headroom for the unexpected — a Black Friday, a viral moment, a market surge.

Business Outcomes We Deliver
60%
Fewer performance defects in production

Shift-left performance testing catches regressions at commit, eliminating costly late-stage fixes and production incidents.

3×
Faster release cycles

Automated performance gates replace manual bottlenecks, accelerating delivery without compromising SLA confidence.

40%
Reduction in cloud infrastructure spend

Capacity planning eliminates over-provisioning while ensuring system headroom for peak demand events.

4.2M
Revenue protected per peak trading event

Validated scalability means Black Friday, sales launches, and market open events run flawlessly — every time.

Client Outcome — Investment Banking

Trading Platform Latency Reduced by 60%, Recovering £4.2M Annually

A tier-1 investment bank's algorithmic trading platform was experiencing latency spikes under peak market open conditions. Missed trade windows were directly measurable as lost revenue. Testhouse's TCoE Performance Architect embedded a shift-left programme across three engineering squads — instrumenting every pipeline stage with performance gates, remodelling load profiles, and identifying a database connection pool misconfiguration causing 80% of the latency events.

NFE Maturity Model — Where Does Your Organisation Sit?
Maturity Level Performance Reliability Security Observability Business Risk
Level 1 — Reactive Ad-hoc testing before release No DR testing Annual pen test only Siloed server monitoring High — incidents discovered by customers
Level 2 — Defined Load tests in staging DR plan exists, untested SAST in pipeline APM on key apps Moderate — issues caught late, costly to fix
Level 3 — Proactive Perf gates in CI/CD Chaos experiments quarterly SAST + DAST in pipeline Full-stack observability Low — issues caught early, rapidly resolved
Level 4 — Continuous Real-time CX + capacity AI Continuous chaos + SLO error budgets Security as code, always-on VAPT AI-powered anomaly prediction Minimal — revenue-protective, regulation-ready
FREQUENTLY ASKED QUESTIONS

Common Questions About Performance and Scalability

Answers to the questions we hear most often from engineering, operations, and technology leaders.

We only run performance tests before go-live. Is that sufficient?
Pre-release testing gives you a snapshot, but not confidence. By the time a performance issue surfaces in staging, it's already expensive to fix. We embed performance gates directly into your CI/CD pipeline, so regressions are caught at code commit, not on the eve of a release. Our clients see up to 60% fewer performance defects reaching production as a result.
How do you define what good performance looks like for our systems?
We start with your business goals, not arbitrary benchmarks. We work with you to define SLAs, SLOs, and SLIs that are tied to revenue outcomes and customer experience targets. This ensures the thresholds your teams test against are the ones that actually matter to the business.
Can you help us optimise cloud costs without sacrificing performance?
Yes. Many organisations over-provision infrastructure by 20–40% out of caution. Through capacity engineering, workload analysis, and realistic load modelling, we help eliminate unnecessary spend while ensuring sufficient headroom to handle peak demand.
How do you approach performance engineering for complex enterprise platforms?
Enterprise platforms such as ERP, core banking, and large-scale digital ecosystems contain multiple dependencies, integrations, and architectural layers. Our engineers analyse application, database, middleware, and integration tiers to identify bottlenecks and optimise end-to-end transaction performance.
