With 1.4 billion listings on eBay, improving the speed to render these listings at scale and accuracy is a huge engineering challenge. We have taken major steps to cache item data, which brings great speed improvements.

The item page is one of the most critical pages in the eBay buyer experience. It's where a buyer make their purchase decisions. It's also one of the pages in eBay that gets the most user traffic.
