Cmake takes close to an hour on RDP

In our environment we have multiple users logging on to our windows remote desktop server and all using CLion at the same time. When testing by self opening a new project takes around 10 seconds. But with ~20-30 users all working on C executables CLion can take over an hour to load a new project. It simply hangs on the Loading Cmake text. I have implemented the work around recommended but whitelisting certain directories from windows defender, this shaved off 30 seconds when testing with just the one user but does not seem to make a difference under load. It is not a processing power issue either as these same servers can handle similar loads running IDEs like visual studio.
