_________________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be suitable for handling real-time audio and other tasks without dropouts. LatencyMon has been analyzing your system for 0:00:27 (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): 412.0 Average measured interrupt to process latency (µs): 14.696427 Highest measured interrupt to DPC latency (µs): 329.70 Average measured interrupt to DPC latency (µs): 3.353165 _________________________________________________________________________________________________________ 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): 209.260 Driver with highest ISR routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation Highest reported total ISR routine time (%): 0.005353 Driver with highest ISR total time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation Total time spent in ISRs (%) 0.012250 ISR count (execution time <250 µs): 1315 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): 444.060 Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification (NDIS), Microsoft Corporation Highest reported total DPC routine time (%): 0.029255 Driver with highest DPC total execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation Total time spent in DPCs (%) 0.130318 DPC count (execution time <250 µs): 11418 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-10000 µs): 59 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: firefox.exe Total number of hard pagefaults 642 Hard pagefault count of hardest hit process: 612 Number of processes hit: 7 _________________________________________________________________________________________________________ PER CPU DATA _________________________________________________________________________________________________________ CPU 0 Interrupt cycle time (s): 0.246243 CPU 0 ISR highest execution time (µs): 209.260 CPU 0 ISR total execution time (s): 0.013145 CPU 0 ISR count: 1238 CPU 0 DPC highest execution time (µs): 444.060 CPU 0 DPC total execution time (s): 0.099144 CPU 0 DPC count: 9472 _________________________________________________________________________________________________________ CPU 1 Interrupt cycle time (s): 0.158333 CPU 1 ISR highest execution time (µs): 4.0150 CPU 1 ISR total execution time (s): 0.000131 CPU 1 ISR count: 47 CPU 1 DPC highest execution time (µs): 434.1350 CPU 1 DPC total execution time (s): 0.012832 CPU 1 DPC count: 563 _________________________________________________________________________________________________________ CPU 2 Interrupt cycle time (s): 0.101325 CPU 2 ISR highest execution time (µs): 4.1750 CPU 2 ISR total execution time (s): 0.000050 CPU 2 ISR count: 21 CPU 2 DPC highest execution time (µs): 85.240 CPU 2 DPC total execution time (s): 0.019717 CPU 2 DPC count: 930 _________________________________________________________________________________________________________ CPU 3 Interrupt cycle time (s): 0.072572 CPU 3 ISR highest execution time (µs): 2.9550 CPU 3 ISR total execution time (s): 0.000019 CPU 3 ISR count: 9 CPU 3 DPC highest execution time (µs): 69.8250 CPU 3 DPC total execution time (s): 0.010271 CPU 3 DPC count: 512 _________________________________________________________________________________________________________
