How else do you use the file server used to store roaming profiles and redirected folders?

Question

Windows Server

There is a file server Windows 2008 R2 RAM - 8GB of memory. Used for storing roaming profiles and redirected folders. Additionally used for 1C file databases (we will consider 1 user - 1 database). And so, periodically there are slowdowns of 1C bases. Moreover, at this time, according to the Task Manager, there is almost no free memory (97-98% is occupied), although this is not visible from the processes. If you look at RAMMAP, then at that time in memory there are sometimes a dozen open pst mail files (Outlook 2010) sometimes reaching 500 MB in size. Looking at this, there are several options:
1. Be patient, accept that this is how it should work with redirected folders.
2. Try to optimize.
3. If patience runs out - move the database to another server.
PS I would be grateful if you explained (confirmed guesses about) the principle of what is happening. I have mail databases open on terminal servers (OUTLOOK.EXE processes hang in memory), the databases themselves lie on the file server (average size is from 3 to 5 GB). I suspect that when someone searches for something in the mail, scrolls, or this is how Outlook is arranged, information from the file server is periodically pulled up, and in the memory of the file server one mail database takes an average of 500MB.
Question: is it possible to somehow regulate this matter, for example, reduce the Mapped File area (from RAMMAP terminology) so that more memory is left for the current file server processes.

Answer 1

What does the file server RAM have to do with running files from this server on the terminal?
right, no
files just lie there
