Stuhloase: load time from 2.8s to 0.7s
With lots of large product images and variants, the shop was noticeably slow. We optimised it technically – the design stayed the same, the load time is much shorter.
The starting point
Stuhloase sells office chairs and ergonomic furniture in a custom-built PHP shop. Many products come in several variants, each with its own large photos. The homepage took 2.8 seconds.
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 custom shop had to get faster without changing the design – despite many large images, variants and external scripts.
- !Many large product images in several variants
- !External scripts slowed down page rendering
- !A custom-built PHP shop instead of a standard system
- !The design had to stay unchanged
What we did
The design stayed unchanged.
Product photos in AVIF, served responsively with lazy loading.
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 →External scripts slimmed down and the load order re-prioritised.
Why it works: External scripts such as tracking or widgets are often the biggest brake. We load them later or leaner, on purpose.

The homepage loads in 0.7 instead of 2.8 seconds. Category and product pages are fast too – with the design unchanged.
