ArcBlock Marketplace — Slow NFT Image Loading & Poor Filter Performance

Summary: The ArcBlock Marketplace (http://marketplace.arcblock.io/) has performance issues when loading NFT images and using filters. Loading is noticeably slower compared to other NFT marketplaces, creating a poor user experience.

Steps to Reproduce:

Open http://marketplace.arcblock.io/.

Navigate to NFT listings (default view).

Observe slow loading time for NFT thumbnails/images.

Apply a filter → Sold Items.

Notice: loading time becomes 2x–5x slower compared to other views.

Expected Result:

NFT images load quickly, similar to other NFT marketplaces.

Filters (e.g., Sold Items) update results instantly or with minimal delay.

Smooth, user-friendly browsing experience.

Actual Result:

NFT images take a long time to render on the page.

Applying filters (especially Sold Items) makes the loading delay significantly worse.

Feels sluggish and unoptimized compared to other NFT platforms.

Impact:

Frustrates users who browse or filter NFTs.

May cause reduced engagement and lower sales since buyers lose patience.

Gives the impression of poor scalability

Severity Classification:

🟠 Medium-High Severity

Reasoning: Not a security bug, but a major UX & performance issue that impacts marketplace adoption.
