I think you posted in the wrong thread David, as your comment has nothing to do with the version of Mono ScreenConnext are using.
We ended up biting the bullet and purchased a Windows Server 2016 license. This has resolved our performance issues and allows for Freshdesk integration. I wish we did this sooner as ScreenConenct was running awful on a Centos 7 x64 machine with 1300 clients.
