Most of the time I use Mission Planner on an old Microsoft Surface 3 - and it has much less performance capabilities than your laptop. Although it’s not very fast, it has always run Mission Planner OK.
I like the Microsoft Surface 3 because it has LTE support for cellular internet connections.
I’m using Mission Planner on the Surface 3 right now - but not connected to a flight controller. It’s using only 10MB according to Task Manager.
I’m interested in finding out what’s causing your situation.
disinstalled, clean with CCleaner, reinstalled. Same situation. Within 60 sec ram goes from 170-180m to 6gb.
I launched firefox and it remain within 400mb constantly
Delete Mission Planner directories from Documents and ProgramData dirs (ProgramData is normally hidden).
Try start Mission Planner without internet connection.
if it runs without internet, then start again when online and when memory usage increased, close it and send MissionPlanner.log files (all of them) from ProgramData/Mission Planner folder.
so after looking at the trace you did, most activity seems to be trying to generate thumbnails of old logs.
normally mission planner will run this, and then create the .jpg thumbnail, and never generate it again until its been removed. have you been deleting the .jpg files that mission planner generates?
