Your Biggest Revenue Day Shouldn't Be Your Biggest Risk.
Festive Readiness for Retail & Ecommerce Teams
A surge in traffic during your biggest sales moments shouldn't expose performance bottlenecks, checkout failures, or slow customer experiences. Testhouse Performance Engineering helps retail and ecommerce organisations validate scalability, uncover risks, and optimise performance before festive demand arrives.
Can you confidently answer these questions?
Slow, fragile, or unprotected systems cost real money.
Performance, reliability, and security aren't three separate problems during festive season — they're one revenue line. These are the numbers retail and ecommerce leaders across the UK, US, India, and GCC are already watching.
£2M+
lost per day for a major UK bank during a load-triggered payment outage at peak — preventable with capacity planning
7%
conversion drop per 1-second latency increase — on a £100M revenue ecommerce site, that's £7M a year
70%
of single outages now cost over $100K, up from 39% in 2019 — and peak trading days carry the highest exposure
63%
of organisations deploy code without fully testing for security — leaving checkout and payment flows exposed exactly when attack traffic peaks
