Heimundgarten24: load time from 5s to 0.5s
A wide catalogue of heavy furniture and garden photos pushed mobile load time to 5 seconds. We optimised it significantly – without changing the tech stack.
The starting point
Heimundgarten24 sells furniture and garden products on PlentyMarkets. The catalogue is wide and the product photos are large and detailed. On mobile, the shop took around 5 seconds to load – from the homepage to the checkout.
On mobile, visitors decide within seconds whether to stay. Every second of waiting costs conversions – and with paid traffic, ad budget too. On top of that, Google rates load time through the Core Web Vitals.
The challenge
The shop had to get noticeably faster – without a relaunch and without changing the tech stack. PlentyMarkets, the design and all workflows had to stay as they were.
- !A wide catalogue with more than 1,800 large product images
- !Around 5 seconds load time on mobile – from the homepage to the checkout
- !No change to the tech stack: PlentyMarkets, design and workflows stay
What we did
Without touching the tech stack.
Over 1,800 product images converted to AVIF automatically and served responsively.
Why it works: AVIF produces much smaller files than JPEG or PNG at the same image quality. Responsive means every device only loads the image size it actually displays.

Why it works: Pages are cached on servers close to the visitor and delivered from there instantly, instead of being rebuilt by the shop system on every request.
Learn more →Load order re-prioritised: visible content loads first, the rest follows.
Why it works: The browser loads what is needed in the visible area first. Scripts and content further down follow without blocking the page from rendering.

On mobile, the shop now loads in 0.5 instead of 5.0 seconds – from the homepage to the checkout. Pages are 78% lighter.
Measured with Real User Monitoring (RUM) – with real visitors.
On mobile, the shop is ready before visitors even start scrolling – all the way to the checkout. Waiting is no longer a reason to drop off.
