Hello,
I try to test SD card performance by following command,
time sh -c "dd if=/dev/zero of=/mnt/mmc/ddfile bs=1M count=100 ; sync"
But, it cause CPU usage is around 40%.
I have same issue like following link

But, the patch is using 2.6.18, does anyone has patch file which is based on 2.6.32?
Thanks,
Thomas.
