1. The performance of Pega software (like any other browser-based software), is dependent upon the browser that it is running on. For the Pega Infinity version 8.1 software, among the browsers we support (listed above), Google Chrome performs the best, both in its rendering performance and its interactivity, as well as being superior in memory management and garbage collection. Mozilla Firefox, Microsoft Edge, and Safari (on Mac) are also closely comparable in performance to Chrome.
Microsoft Internet Explorer 11 performs the worst among all the supported browsers. Other browsers have innovated heavily over the last few years, while Internet Explorer 11 is purely in maintenance mode. It uses an old and proprietary rendering engine, runs as a single process on the operating system, and has suboptimal memory management. We do continue to support Internet Explorer 11, as many of our customers have standardized on IE11 due to other legacy software that only works on Internet Explorer 11 and prior versions of Internet Explorer.
For Pega Infinity, we recommend that our customers move away from Internet Explorer 11 in favor of using Chrome, Firefox, or Edge on Windows, to get the best performance from their Pega applications.
For Pega 7.3.1 do I consider that the same paragraph below applies when it comes to IE11?

We don't mind telling the clients to move away from IE, but if they asked why? Especially that they are using it as their daily driver, for basic stuff and it suits them. The problem is that you don't have control over all the clients.
we can easily redirect them for awareness to the page I shared above if and only if we were using 8.1 because the page is for 8.1
But there is no document with the same information dedicated for Pega 7.3.1
Well I understand your position, but as I said, I think this is regardless of the Pega version. Actually it is even regardless of Pega. If you search on internet you will find a lot of discussions about IE11 performance.
