ADC Conversion timing issue

Hi Team,

1. In S32K146, I have an issue where ADC0 (total 8 channels) one-shot conversion takes ~600 microsec for a single group using StartGroup() & ReadGroup() Apis and this is causing timing delays for the 1ms App scheduler. 
What could be the reason for this timing behaviour?

2. When I changed the config to Continuous mode , the time delay was ~120ms for getting the expected ADC value increased compared to one-shot where it took less than 50msec, is this expected behaviour.
 
3.After analyzing the timing for the internal ADC functions , it was found that the Adc_Ipw_ConfigurePdbConversion(), ADC_Ip_ConfigChannel() is taking 130 us, 120 us which causes overall timing delay.
