All support articles are affected.While that is being sorted out, can you clarify the use cases in question here?I take it you are experiencing general performance issues in designer studio.Your comments imply IE9 is one of your used browsers.Are you seeing performance issues with other browsers as well, or is it specific to IE? or even IE9 specifically? Posted: 4 years agoTAMAGCAOILI National Express Corp replied to RettanahHeanit's specific to IE9. the developer studio is fast enough in FireFox but updating UI elements are mostly done in IE. Posted: 4 years agoRettanahHean replied to TAMAGCAOILIPDN is back up. So if you have confirmed this issue is specific to IE9, and this SA (https://pdn.pega.com/support-articles/pega-717-performance-poor-ie-9) matches your symptoms, you can open an SR to request this HFix to see if it addresses your issue.
