Latency when switching between Account tabs



Browser refresh is slow when using the Tabbed screen flow. On selecting a tab in a group of multiple (more than five or six) tabs, the browser takes seven seconds to refresh the display.  The browser must display the refreshed tab in two seconds.
While the tab is refreshed, stale or incorrect data display.

Steps to Reproduce

  1. Accept a Computer Telephony Integration (CTI) screen pop incoming telephone request.
  2. Open multiple screen flow tabs.  
  3. Wait for approximately 10 seconds (that is, talking to the incoming call).
  4. Select different tabs based on the conversation. The tabs refresh based on the selection made from other tabs.

Root Cause

Switching tabs caused a refresh in the Clipboard. The pzUpdateClipboardModel activity was executed multiple times for a single tab. This impacted the performance.


  1. Apply HFix-40450 (to implement a new API to reduce Clipboard Updates when switching tabs).
  2. Apply HFix-40449 (to reduce calls to pzUpdateClipboardModels on the Interaction tab switch).
