The thing that bothered me in my test results was the fact that the CPU usage was so high when using the crypto engine. Part of the point behind such engines isn't just to accelerate the crypto handling, but also to free up the CPU for other tasks while it handles the crypto. The fact the second core was loaded that much then was puzzling. Could be that BCM's engine implementation sucks. Maybe Asus is also suspecting something there as they asked me to include CPU usage results when I submitted benchmark results to them.I mean that crypto engine [bcmspu (crypto driver) + bcmpdc (parallel encryption)] seems just only did parallel encryption.
