Is rtems interrupt latency good enough for BLDC ESC? (on arm cortex-M or cortex-R)

Just Curious,

As for the title.

I found an old article:,
it said rtems's interrupt latency on MC68020 is The maximum period with
interrupts disabled + 9 microseconds on 20Mhz.

I see zephyr provided a "Zero-Latency interrupt" facility to do with near
bare metal performance interrupt handler,  and a talk is about using
Zero-Latency Interrupts feature to make a ESC with ZephyRTOS.

Is rtems good enough to do the same thing?
