Features that are good to consider for faster QN908x as a central device

Would like to know the list of features that I need to enable/consider to make the QN908x quick start and connect to the whitelisted MAC address devices.

 

Few of the features which I know might have impact on the setup are:
 1. BLE Antenna design - Is there any specific Antenna design needs to be followed for the Central BLE Device.
 2. BLE Clock by default set to 8MHz is there any advantage by setting it to 16MHz.

 3. Since boot up time has to optimized  as much as possible - does it make a difference by skipping the NVDS read for CAPs. 
4. It will be very helpful if there is a performance chart or timing chart showing the time QN908x controller takes to boot up, initialize the BLE stack. 


Our requirement is to make the connection with the white listed BLE Peripheral device and exchange three sets of data packets of size 20 bytes each.
