Interrupt latency for PowerPC

I am looking for interrupt latency numbers for PowerPC architectures, if possible for e500v2.Looking at below postings, there is a mentioning of "TBD" microseconds as maximum period ... and a variable "na" to describe the value of MHz.Can you please share your experience ? https://docs.rtems.
