Most of you know that one of the most important user experience metrics in a Citrix environment is the logon time. A 2018 survey by eG Innovations and DABCC found out that Citrix logon time was the number one problem for administrators: 59% of respondents rated logon time as their biggest problem. There are many best practices to improve Citrix logon times. Slowness during the logon processing can, of course, increase logon times. Issues with group policies or slow profile loading is often a cause.
