I was performing some routine maintenance (deleting cache, etc) in order to keep my v12.4.3. 5S running as well as can reasonably be expected when I noticed that the lowest that I can force RAM utilization down to is around 70%. This is with only one app running, Status Monitor by techet.net. I get similar results with other system monitors (SmartMemory and RefreshEd). I've done a search to try to find out if this is a reasonable 'lowest' level of RAM utilization but was surprised to come up empty. Apparently, I'm not searching correctly for the v12.4.3 RAM footprint. Can any of you please give me a hint as to how to find this info? To clarify, I am not asking for help troubleshooting anything. There are a few functions that work in a flaky fashion (and which could conceivably be aggravated by improper RAM utilization, I suppose), but this particular exercise is proactive-oriented and one of self-education. Thanks in advance for any pointers!
