_________________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be suitable for handling real-time audio and other tasks without dropouts. LatencyMon has been analyzing your system for 0:00:40 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: LAPTOP-U5DF9B48 OS version: Windows 10, 10.0, version 1909, build: 18363 (x64) Hardware: HP Laptop 15-db0xxx, HP CPU: AuthenticAMD AMD A6-9225 RADEON R4, 5 COMPUTE CORES 2C+3G Logical processors: 2 Processor groups: 1 RAM: 7645 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 2595 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): 764.70 Average measured interrupt to process latency (µs): 9.422191 Highest measured interrupt to DPC latency (µs): 228.50 Average measured interrupt to DPC latency (µs): 3.473942 _________________________________________________________________________________________________________ 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): 78.571098 Driver with highest ISR routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation Highest reported total ISR routine time (%): 0.028642 Driver with highest ISR total time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation Total time spent in ISRs (%) 0.030528 ISR count (execution time <250 µs): 2786 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): 545.556840 Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation Highest reported total DPC routine time (%): 0.129866 Driver with highest DPC total execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Total time spent in DPCs (%) 0.450288 DPC count (execution time <250 µs): 34365 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-10000 µs): 67 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: registry Total number of hard pagefaults 165 Hard pagefault count of hardest hit process: 48 Number of processes hit: 11 _________________________________________________________________________________________________________ PER CPU DATA _________________________________________________________________________________________________________ CPU 0 Interrupt cycle time (s): 0.617091 CPU 0 ISR highest execution time (µs): 78.571098 CPU 0 ISR total execution time (s): 0.020051 CPU 0 ISR count: 2118 CPU 0 DPC highest execution time (µs): 509.544509 CPU 0 DPC total execution time (s): 0.264095 CPU 0 DPC count: 25984 _________________________________________________________________________________________________________ CPU 1 Interrupt cycle time (s): 0.455201 CPU 1 ISR highest execution time (µs): 61.480925 CPU 1 ISR total execution time (s): 0.004448 CPU 1 ISR count: 668 CPU 1 DPC highest execution time (µs): 545.556840 CPU 1 DPC total execution time (s): 0.097261 CPU 1 DPC count: 8448 _________________________________________________________________________________________________________
