Performance

How Aisleza stays light on your site and smooth on every screen, and what you can do to help.

Loading#

• Scripts load only on the store page: about 30 KB with the page.
• The 3D engine (about 140 KB compressed) loads only when a shopper walks in.
• Shelves load one page of products at a time.

Drawing#

• Static geometry is merged by material: a full store is drawn in around a hundred draw calls.
• Nothing is drawn while the shopper stands still.
• A pixel budget and adaptive quality keep large and 4K screens smooth; quality settles a moment after resizing.
• Phones get a lighter view, and thin details become pictures so they don’t shimmer.
• Every skin is tested walking on a phone with a 4× slowed processor: the slowest frames stay around 10 ms.

Video#

Only a couple of YouTube players run at once (one on phones), screens in view come first, and muted videos out of view are paused.

Tips#

• Use product images around 800–1200 px; very large originals are fine, WordPress serves smaller sizes.
• Keep Products per shelf moderate.
• Use MP4 (H.264) for Media Library videos.
