This is the opposite of https://community.esri.com/t5/arcgis-pro-ideas/arcgis-pro-power-saving-mode/idi-p/1407823
In many parts of the Pro UI it seems like Esri uses some form of aggressive memory offload to make it behave better on lower spec machines. I assume this is why some UI panels or windows are sluggish to appear when you have not used them for a few minutes, even on very high spec machines.
A good example is the behaviour of the Symbology Gallery when you click on a layer's symbol - it may take a second or so to load all the symbols you have available.
For users with very high spec computers create a Pro mode that does not offload anything - Just keep loading things into RAM and keep them available until you hit 80% or so. (read the ZFS docs for tips....)
I want to be able to have things show up immediately and wouldn't mind if Pro takes up a bunch of RAM to make it sing. Most of my day to day work is on smaller projects with lots of variability and lots of map output and not on massive datasets. Being able to quickly open maps and change symbols, add layers, filter layers, add symbology, etc. is more important to me for improvement than crunching a statewide property database - that is fast enough already.
Make it a selectable setting for users with a lot of RAM, say 128 or 256GB. I am writing this with 2 Pro & 1 ArcMap sessions open, too many browser tabs open in 2 browsers, along with a few other nick nacks & have about 90% RAM free.
