Root Cause

In the design, the harness/section has multiple Layout group tabs and each tab has a grid which increases the number of components in a page. This affected the overall rendering performance.
Hence, it is recommended to remove the LiveUI and enable the 'Defer Load' option on the layout group tabs such that the tabs contents is loaded lazily on demand.
The Internet Explorer is slow because it has a different JavaScript Runtime and renders the engine unlike Chrome which is based out of the standard 'WebKit' engine which is fast. Therefore, when compared to Chrome, the Internet Explorer browser performance degrades (this is expected).


Perform the following local-change:
  1. Defer Load the layout groups.
  2. Remove the Live UI.
