How are you measuring the 1-second delay time ? I suppose you measured the time taken between starting the scan and receiving the scan response, is this right ? In the link layer, the scan response is received after T_IFS but I suppose it will take some time for the event to reach the application level.
The best way to find out the exact time difference between the scan request and scan response is to sniff the packets over the air.
