I purchased an SER8 8745HS to produce music. I’ll be using Studio One Pro and a digital audio interface. I ran ‘Latency Monitor’ and received the following report (below) .
What do you attribute to the poor performance and what can be done to correct this ?
Thank you…
Report:
CONCLUSION
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:03:25 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 1139.50
Average measured interrupt to process latency (µs): 41.538643
Highest measured interrupt to DPC latency (µs): 985.60
Average measured interrupt to DPC latency (µs): 25.825549
REPORTED ISRs
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.
Highest ISR routine execution time (µs): 280.035856
Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Highest reported total ISR routine time (%): 0.034957
Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Total time spent in ISRs (%) 0.034957
ISR count (execution time <250 µs): 91118
ISR count (execution time 250-500 µs): 0

ISR count (execution time 1000-2000 µs): 0
ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0
REPORTED DPCs
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.
Highest DPC routine execution time (µs): 1198.036910
Driver with highest DPC routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Highest reported total DPC routine time (%): 0.010795

DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 110
DPC count (execution time 1000-2000 µs): 1
DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 µs): 0
REPORTED HARD PAGEFAULTS
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: msmpeng.exe
Total number of hard pagefaults 166
Hard pagefault count of hardest hit process: 154
Number of processes hit: 2
