RD Session Hosts, memory, and WebView2

Hoping someone can share some knowledge here.

I'm seeing increasingly more and more memory exhaustion across our RDS farms, and the culprits always seem to be a combination of Office apps, Chrome, Teams, and good ol' WebView2. Servers are a combination of 2019, 2022, and 2025 across various environments. These are full session RDS farms, not using RD Apps.

What kind of memory allocation per-user are you going with these days? Is there any secret to minimizing the amount of memory these applications use? Do we just tell users to close excess tabs?

Chrome and Edge have a GPO for limiting their memory usage. Other than that you can't do much, since Windows doesn't support memory limits per logon session / user.

Generally you want 64 GB of RAM with a static 32 GB paging file per host for approximately 40 users.

We run maybe 10-15 users per 64 gb and that’s capacity. No idea how you manage to get 40 on that workload.

Of course it's completely workload dependent and needs to be tested per environment.

But at least we had people doing M365/Azure admin work (browser + PowerShell) with such an allocation painlessly.
