Hi,

Most UVC (USB video class) drivers use direct memory mapping, so there 
shouldn't be a significant performance improvement in that case. If you are 
using DVB USB drivers, that might be different. Maybe you have to use the 
"time" utility to measure the difference, like starting webcamd like this:

time webcamd -H

Then run pwcview for 5 minutes. Then CTRL+C webcamd.
