Description Samuel Padgett 2020-01-07 21:00:25 UTC 
The OperatorHub subscribe flow is blocked until all images from the catalog load. Since we do code splitting, the request for the JS chunk for the next page is blocked because of the pending image requests. This has also caused timeouts in our OLM integration tests in CI.
Comment 1 Samuel Padgett 2020-01-07 21:05:32 UTC 
The fix we made was to lazy load the icons as the user scrolls. Only the icons visible on the page (and some a bit below the fold) are loaded.
Comment 3 Yanping Zhang 2020-01-08 06:25:48 UTC 
Checked on OCP 4.3 env with payload 4.3.0-0.nightly-2020-01-07-212456, open OperatorHub page, after about 4 seconds, items are loaded, and when user scrolls down the page, could see item and choose item smoothly. The performance has been enhanced.
