User portal performance 7.1.6

SA-1889

Summary



When users log into the user portal using Internet Explorer version 8 (IE 8) or some versions of IE 9 the portal performs unacceptably slow. This issue is does not occur in Chrome and newer versions of IE.

Error Messages



No error message. Observed degraded performance on IE 8 and IE 9.


Steps to Reproduce



Case manager portal loaded into using IE 8 and IE 9.


Root Cause



The root cause of this problem is a known issue with client side performance while using IE8 to access PRPC v7.1.  It was not confirmed that the issue occurred with IE9.

Resolution



There is a known issue with client side performance while using IE8 to access PRPC v7.1. This is mentioned in the following section in the platform support guide (https://pdn.pega.com/documents/platform-support-guide-for-prpc) - see page 12, number 3.
 
IE8 continues to work with v7.1 with the caveat that IE8 is known to cause client-side performance issues when operating in Standards Mode. Some screens, especially grids and lists which display large amounts of data, may experience sub-optimal performance with IE8. We strongly recommend using another browser which does not have these performance issues, such as IE9, IE10, IE11, Chrome, Safari, or Firefox. Microsoft is no longer updating IE8, and instead points customers to IE10 or IE11. Therefore, Pegasystems cannot address these client-side performance issues reported with IE8. Customers should consider carefully before using IE8 as the target browser with v7.1.
