Join an eye-opening conversation that clears the fog around two buzzed-about terms –

Performance Engineering and Performance Testing. They may sound similar, but their impact on software delivery couldn’t be more different.

About the Episode:

Most teams think of performance only when a build is nearly complete, but by then, bottlenecks are harder and costlier to fix. That’s where Performance Engineering steps in to build speed, stability, and scalability right from the start of the software lifecycle. Performance Testing, on the other hand, validates those systems under real-world loads to confirm they can hold up when it matters most. 

In this episode, Nagarjuna Etea (Associate Director, Performance Engineering at ImpactQA) and Richa Bajaj (Associate QA Manager at ImpactQA) break down why organizations need both approaches working together. From AI-driven analytics and predictive modeling to self-healing automation, they share how businesses are shifting from “testing performance” to “engineering performance” – a shift that blends strategy with execution. Listeners can expect practical insights, real-world examples, and a sharper perspective on delivering speed with confidence.

What You’ll Learn 

• The difference between Performance Engineering (proactive) and Performance Testing (reactive) 

• Why timing across the SDLC changes everything for performance outcomes 

• How AI enables predictive analytics, adaptive load simulation, and anomaly detection

• Key testing types and their real-world value 

• Business impact: how SPE lowers late-stage costs while SPT validates readiness before release 

Key Takeaways for Digital Leaders

• Engineer Early: Build holistic performance models early to prevent late-stage issues

• Test Effectively: Validate user experiences under real workloads before release 

• Adopt AI: Use self-healing automation, anomaly detection, and auto-generated scripts 

• Think Holistic: SPE and SPT work together and not in silos for sustainable digital delivery
