See DPC spikes on the order if 2000 to 3000 uSec (2 to 3 mS), Interrupt to process latency hovering around 20000 to 30000 uS (20 to 30 ms). Not good for realtime audio processing. WebA major contributor to increased interrupt latency is the number and length of regions in which the kernel disables interrupts. By disabling inter- rupts, the kernel may delay the handling of high priori- ty interrupt requests that arrive in those windows in which interrupts are disabled.
