at idle, my RPi2 hovers around 7%, either on a single core, or split between two cores, such as 5% and 2%

note that using something like #bcmstat.sh p produces noticeably higher CPU load than #top and then pressing 1 to see the individual CPUs

Thanks. After letting my RPI2 sit idle all night, it's showing about 15% idle CPU usage (using 'top' over SSH).

However, I'm still wondering if it's normal to see [Buffering...] for a few seconds when seeking around very large files. I'm using wired gigabit Ethernet and NFS. My over HTPC seeks around pretty much instantly.

EDIT: Also, I am using a 64 GB Samsung microSD card because I didn't have anything else available. I've ordered the NOOBS card directly from RPi foundation because I heard that's a very good card, but could my existing card be causing some of this buffering?
