Huge memory consumption kernel_task and taskgated

What else did you get all that memory for... just to sit idle?

You memory misers crack me up.

 

From what I can gather, Mavx seems to use about 90% of your RAM. Generally. All the time. Whatever you're doing.

If you have a problem with performance, then you can consider whether there's any merit in investigating each process's memory usage. Otherwise: relax. There's a computer looking after your memory.
