Highest measured interrupt to process latency is at 10405.20

[xilolee]

Is the problem still present?

More information from the developer (?): Windows: Line-Based vs. Message Signaled-Based Interrupts. MSI tool.
I scanned the zipped file with virustotal, jotti, metadefender, windows defender, malwarebytes, superantispyware: always clean.

Run it as an administrator.
Take a screenshot and post it here.
It seems you can quite safely change the msi mode checkbox for the HD audio controller from unticked to ticked.

 

[Itamar]

I have ticked it as you told me to




could you tell me what this is supposed to do or how it is supposed to help?

 

[Itamar]

BTW i still get high dpc latency just not that bad anymore it is mostly due to these drivers:


do you have any knowlage about fixing thse two drivers or reducing their dpc latency?

here are the diagnostics:

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): 701.80
Average measured interrupt to process latency (µs): 6.399648

Highest measured interrupt to DPC latency (µs): 700.0
Average measured interrupt to DPC latency (µs): 3.375782


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%): 0.033427
Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%) 0.033596

ISR count (execution time <250 µs): 387267

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): 567.001108
Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation

Highest reported total DPC routine time (%): 0.026092

DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 15
DPC count (execution time 1000-2000 µs): 0
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: backgroundtaskhost.exe

Total number of hard pagefaults 1104
Hard pagefault count of hardest hit process: 974
Number of processes hit: 7

thank you for all of the help up until now!

 

[xilolee]

My results are worse than yours, maybe you should be the one to help me.



If there are no more stutters and popping sounds, uninstall latencymon.

 

[Itamar]

there is one or two stutters every now and then but it is so much better then before
, i will keep this thread unresolved to update if needed if you dont mind.

thank you for all of the help xilolee!

 

[Itamar]

but just for my personal knowledge in the field, what is an IRQ?
