This is a M4 iMac 32GB 2TB where over the last few months memory use has been crazy. The worst offender is SimulatorTrampoline. I just opened a default iOS app and ran it in a simulator. So this is as simple as it gets: there's 1 SF Symbol and "Hello, world!" text.

iStatMenus shows SimulatorTrampoline at 10.7GB, Safari 5.2GB, Xcode at 3.2GB, and swap at 548MB

meanwhile ActivityMonitor shows the top memory use of Ildb-rpc-server at 2.30GB, Xcode at 523.4MB Swap is 548MB is the only number that matches and the fact that Memory used is ~26GB total.

Is this amount of memory use normal? Is iStat menu reporting something different than Activity monitor. This computer used to never swap. Any suggestions?

I did find that iStat menus has a setting to "Combine Processes" so it's creating sort of a compilation that explains why ActivityMonitor is different. Still, if all these simulator processes add up to 10GB it still seems like a lot.
