_________________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be suitable for handling real-time audio and other tasks without dropouts. LatencyMon has been analyzing your system for 1:39:22 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: DESKTOP-6ICJV2A OS version: Windows 10, 10.0, version 1909, build: 18363 (x64) Hardware: System Product Name, System manufacturer CPU: AuthenticAMD AMD Ryzen 7 3700X 8-Core Processor Logical processors: 16 Processor groups: 1 RAM: 16318 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 3593 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): 490.30 Average measured interrupt to process latency (µs): 4.645958 Highest measured interrupt to DPC latency (µs): 485.40 Average measured interrupt to DPC latency (µs): 2.332104 _________________________________________________________________________________________________________ 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): 163.678263 Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Highest reported total ISR routine time (%): 0.117163 Driver with highest ISR total time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Total time spent in ISRs (%) 0.123755 ISR count (execution time <250 µs): 9867494 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): 472.739215 Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation Highest reported total DPC routine time (%): 0.066020 Driver with highest DPC total execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Total time spent in DPCs (%) 0.185439 DPC count (execution time <250 µs): 28503657 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-10000 µs): 389 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: chrome.exe Total number of hard pagefaults 54504 Hard pagefault count of hardest hit process: 4635 Number of processes hit: 175
