After RFE answered for H1 stamping interview how many days for visa application to update the status

Interview on 8th Feb 2013

RFE answered on 21st Feb 2013

Application status on ceac... site.. Updated on 8th Feb :"Administrative Processing...''

After that no update

How much time does it take to clear the application.

Is there any way to speed up the process.

Thanks
