Re: [Gems-users] Very high cache miss overhead

That means those are generated by some OS background process. You can  
either let it run functionally for a while until the system becomes  
idle (then make a checkpoint), or reboot the simulated system. I  
personally never had such issue - I always just boot the machine to  
get an idle system.
