slow server response time
Uncached dynamic requests and slow hosting increase Time to First Byte across key pages.
app script overload

oversized product images
Large product media increases transfer weight and slows both mobile and desktop category pages.
theme code bloat
Legacy theme snippets and unused sections create unnecessary CSS and JavaScript payloads.
widget overload

autoplay media backgrounds
Autoplay videos and heavy background media consume bandwidth and hurt mobile responsiveness.
