Subject: Unable to achieve 30fps using 'read()' in C

Hi all, I am new in v4l programming. What I did in my code is I used 'read( )' in C programming to read images from my Logitech Quickcam Express. My problem is I can't get 30frames per second, what I got is just 5fps when I loop and read for 200times. Do anyone know why is it under performance? Thanks
Rgds,
