modify calling frequency of nus_data_handler()

Question

Hello, 
 I'm new to BLE. I am using nRF51822. Is it possible to modify calling frequency of nus_data_handler() so that I can deal with data coming from BLE faster?
How can I find API document of s110 SoftDevice version 6.0.0? 
 Thanks.

Actually nus_data_handler() was frequent enough. The slow part was BLE communication.
I was using a Galaxy Note 2 ( a special version only for development ) with android 4.3. And with this phone, the minimum interval time is 50ms.
At first I thought nus_data_handler() was being called every 50ms, but the truth is that BLE communication itself receives every 50ms.
So this topic is end.
Thanks
