How to optimize finisher.sigma.vercel.app
LCP element has 2.9 seconds of render delay preventing fast visual completion.

This Next.js site has good performance with a score of 83/100, but there are several opportunities for improvement. The biggest issue is oversized images that are wasting 201 KiB of bandwidth and delaying your Largest Contentful Paint by 300ms - particularly one image that's being served at 1920x1456 pixels but only displayed at 665x1182. Additionally, there's 28 KiB of unused JavaScript code that could be removed or deferred to save another 150ms. Implementing responsive images and cleaning up unnecessary JavaScript could easily push your score into the 90s and provide a noticeably faster user experience.
Why It Matters:
Images are oversized for their display dimensions, wasting 201 KiB and delaying LCP by 300ms.
How to Fix:
Configure Next.js Image component with proper responsive sizes prop. Update the CloudFront image with width=665 instead of 1920. Use Next.js built-in image optimization with format='avif' and quality=80 for automatic compression.
Why It Matters:
28 KiB of unused JavaScript delays LCP by 150ms and blocks page interactivity.
How to Fix:
Analyze the Next.js chunk file to identify unused components and libraries. Use dynamic imports with React.lazy() for components below the fold. Configure Next.js bundle analyzer to identify and tree-shake unused dependencies from the build.
Once your site is optimized, maintain that speed. Use DeployHQ for zero-downtime, automated deployments—so performance fixes and updates go live safely every time, without breaking your site.
