_________________________________________________________________________________________________________ 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 0:00:31 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: PINKYPC OS version: Windows 10, 10.0, version 2009, build: 19042 (x64) Hardware: Aspire E5-573, Acer CPU: GenuineIntel Intel(R) Core(TM) i3-5005U CPU @ 2.00GHz Logical processors: 4 Processor groups: 1 RAM: 4016 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 20 MHz Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results. _________________________________________________________________________________________________________ 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): 542.70 Average measured interrupt to process latency (µs): 11.869747 Highest measured interrupt to DPC latency (µs): 493.40 Average measured interrupt to DPC latency (µs): 3.057704 _________________________________________________________________________________________________________ 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): 39.3650 Driver with highest ISR routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation Highest reported total ISR routine time (%): 0.005584 Driver with highest ISR total time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation Total time spent in ISRs (%) 0.012662 ISR count (execution time <250 µs): 1657 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-1000 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): 1467.80 Driver with highest DPC routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation Highest reported total DPC routine time (%): 0.097685 Driver with highest DPC total execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation Total time spent in DPCs (%) 0.235859 DPC count (execution time <250 µs): 20721 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-10000 µs): 74 DPC count (execution time 1000-2000 µs): 2 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.
