08/21/2025, 9:50 PMThey could re word a little better, like: Optimize only if system has this much available ram left for all the greedy apps 🙂
Funny how you cant set it to more then 4000. What if i want to kick in when their is only 6000mb left to give uers

08/21/2025, 10:08 PMIt basically forces apps to unload from physical memory which can push them to use the Page File instead. We had to increase our Page File size in order for this feature to play nice. Also, our page files live on temp storage in Azure, so it shouldn't interrupt the OS drive performance, I assume.

Premium disk IO is usually decent enough (depends on the size of course) and it has burst capability so that helps

08/22/2025, 2:40 PM@Jeff Riechers Where is Ram compression? And what do you mean by you kick that into play when it gets to 256?

Have a bunch of empty ram doesn't improve performance of day to day usage. Only provides a benefit when you go to open a large amount of data and it needs the ram.
