Why store speed is a selling feature, not a technical luxury

When a merchant buys a theme, they are buying a storefront. But a storefront that needs four seconds to appear is not a storefront, it is a white screen. Speed is a design decision made at the first line.

Where the time actually goes

In most slow stores the problem is not the server. It is three things: images larger than their display size, fonts loading weights nobody uses, and JavaScript libraries loaded on every page though they serve one.

What we do differently

• A separate script per page, so the product page never loads cart code
• Limited font weights with separate Arabic and Latin subsets
• Explicit dimensions on every image to prevent layout shift while loading
• Reusing the libraries Salla already bundles instead of adding a second copy

How to measure your own store

Open your store on a real phone over ordinary mobile data, not on your fibre-connected desktop. Then run Lighthouse in mobile mode. The number you see is the one your customer experiences.
