Rstudio memory usage sky high


In our company we use Rstudio version 1.3.1073 and R version 4.02. We run it as a Citrix published app installed on a Windows 2016 server.

Memory usage is sky high. Some sessions use about 25GB of memory. Is this normal? Or is there something to do to fix this?

What is the best way to run Rstudio? Is it compatible with Citrix and Windows Server? Or should we run it locally on our Windows 10 laptops?
