WIZICO Performance

Load Testing

We verify system readiness for peak loads. Find bottlenecks, provide optimization recommendations.

Why work with us

Design before development

We start with understanding the task. No code until we design.

Architecture for scale

We build scalability from day one.

One team

The same people who designed — build and take responsibility.

Modern load testing

JMeter

Enterprise load testing

Grafana

Metrics visualization

Prometheus

Metrics collection

We stress-test systems before production. Clear recommendations.

Reports & documentation

We don't start with code. Start with discussing your project.

Questions & Answers

How does site speed affect sales?

What are Core Web Vitals?

How do you speed up databases?

Can you optimize legacy code?

What result do you guarantee?

How does site speed affect sales?: According to Google/Deloitte, speeding up a mobile site by 0.1s increases conversion by 8.4% in retail. A slow site literally loses money.
What are Core Web Vitals?: These are Google metrics (LCP, FID, CLS) evaluating UX quality. Since 2021, this is an official SEO ranking factor. We bring sites into the 'green zone' (90+ points).
How do you speed up databases?: We analyze slow queries, add indexes, set up caching (Redis), sharding, and replication. We optimize the DB structure itself.
Can you optimize legacy code?: Yes, we profile code, find bottlenecks, refactor algorithms, and get rid of N+1 queries.
What result do you guarantee?: We fix target metrics (e.g., Time to First Byte < 200ms, Google PageSpeed > 90) in the contract and work until they are achieved.

First we diagnose and design. Then we build with engineering responsibility.
