PerformanceFlex

Performance testing on demand, delivered at scale

Flexible, cost-effective performance assurance for digital platforms

Digital systems are expected to perform flawlessly under pressure – but traditional performance testing is often expensive, slow to scale, and limited by internal tools or infrastructure. This leads to late discovery of performance issues, unexpected outages, and increased business risk.

PerformanceFlex solves this with cost-effective, on-demand performance testing delivered via the Assurity Cloud. Test at scale, identify bottlenecks early, and validate your systems under real-world load – without the overhead of managing tools or environments.

Key benefits

Significant cost savings

Cut performance testing costs by up to 70% with flexible, on-demand services – no infrastructure or licences required.

Early risk mitigation

Detect performance issues early in delivery to avoid costly rework and protect system stability before go-live.

Scalable, real-world testing

Test from outside your network under real-world loads to validate performance at scale – including peak traffic conditions.

Platform features

Expert performance analysis

Gain deep insights into system behaviour with expert-led analysis of non-functional requirements, workload patterns, and performance metrics.

Realistic workload modelling

Simulate real-world usage with data-driven workload models that reflect actual user behaviour and business-critical scenarios.

Synthetic traffic generation

Create synthetic workloads to test system resilience under varying load conditions, using protocol-level simulations for accuracy.

Bottleneck detection and optimisation

Identify performance bottlenecks across complex technology stacks and receive actionable recommendations to improve system responsiveness.

Peak load and stress validation

Verify system stability and scalability under peak business loads to ensure consistent performance during critical periods.

Dynamic dashboards and reports

For fast feedback and on-the-fly refinement of results.

Engagement models

We offer flexible engagement models to suit your delivery environment, project scope, and quality goals.

On-demand (pay-per-use)

What clients say

“Previously, we worked on confidence alone. With metrics, we know how the system will respond and where its breaking point sits. It’s the power to know.”

Talent Management Leader

“The main benefit was acceleration. We can onboard new parties rapidly by enabling them to self-service with testing. Having the right information makes testing easier for them and us, so both parties win.”

Chris Hourigan

Business Transformation Test Lead, Inland Revenue

“We’re building internal testing capability, including introducing an automated performance testing environment. The fact that Assurity is willing to share their knowledge and help us create a strong team of testers says a lot about their view on creating and exchanging lasting value.”

Shane Gaskin

CIO, NZQA

Automation means we can test continuously across
all services, while at the same time, partners access the DPS test assets from the cloud, testing from their perspective.”
