Technical data

# Verifiable performance.

Vokzar does not sell the feeling of speed. We measure transfer weight, response time, mobile experience, visual integrity, and technical efficiency.

## A Vokzar page vs a typical site

The full track represents a typical unoptimised site. The filled part is a Vokzar page.

Methodology

## How we measure before claiming.

Condition: measure the published page, mobile device, simulated network, and visible test date.

Tools: PageSpeed Insights, Lighthouse, WebPageTest, Search Console, and CrUX when enough field data exists.

Comparison: separate transfer weight, LCP, INP, CLS, TTFB, and visual quality. Do not mix perception with evidence.

Validation: repeat after deployment, confirm indexation, and document regressions before publishing claims.

Payload efficiency

## Lower weight, cleaner mobile UX.

Many websites ship visual files with unnecessary weight, metadata, dimensions, or loading behavior. Technical optimization reduces that waste without harming the useful visual signal.

Common media payload 840 KB

Optimized media target 32 KB

-60-90%

## Performance knowledge base

### How can a site be faster than a standard CDN?

The difference is not cache alone. It is the real file weight, format strategy, delivery behavior, and reduction of unnecessary browser work.

### Does advanced compression hurt visual quality?

The goal is to reduce weight while keeping the useful detail. Validation should compare perceived quality, usage context, and mobile impact.

### What is the ROI of performance optimization?

It depends on traffic, current page weight, conversion rate, and infrastructure cost. The usual signals are lower transfer, cleaner LCP, and better mobile experience.

### Why did INP replace FID as a Core Web Vital?

INP measures responsiveness to real interactions across the page lifecycle, making it a more complete user experience metric.
