_________________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be suitable for handling real-time audio and other tasks without dropouts. LatencyMon has been analyzing your system for 0:00:21 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: ACER OS version: Windows 10 , 10.0, build: 17134 (x64) Hardware: Aspire TC-605, Acer CPU: GenuineIntel Intel(R) Core(TM) i3-4150 CPU @ 3.50GHz Logical processors: 4 Processor groups: 1 RAM: 3905 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 3492 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. WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature. _________________________________________________________________________________________________________ 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): 281.517827 Average measured interrupt to process latency (µs): 18.382069 Highest measured interrupt to DPC latency (µs): 268.908174 Average measured interrupt to DPC latency (µs): 5.238366 _________________________________________________________________________________________________________ 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): 34.799542 Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation Highest reported total ISR routine time (%): 0.023922 Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation Total time spent in ISRs (%) 0.028798 ISR count (execution time <250 µs): 10655 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-999 µs): 0 ISR count (execution time 1000-1999 µs): 0 ISR count (execution time 2000-3999 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): 309.522337 Driver with highest DPC routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation Highest reported total DPC routine time (%): 0.285718 Driver with highest DPC total execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation Total time spent in DPCs (%) 0.343713 DPC count (execution time <250 µs): 14839 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-999 µs): 2 DPC count (execution time 1000-1999 µs): 0 DPC count (execution time 2000-3999 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: avp.exe Total number of hard pagefaults 8 Hard pagefault count of hardest hit process: 5 Number of processes hit: 2 _________________________________________________________________________________________________________ PER CPU DATA _________________________________________________________________________________________________________ CPU 0 Interrupt cycle time (s): 0.544467 CPU 0 ISR highest execution time (µs): 34.799542 CPU 0 ISR total execution time (s): 0.021619 CPU 0 ISR count: 8815 CPU 0 DPC highest execution time (µs): 309.522337 CPU 0 DPC total execution time (s): 0.280875 CPU 0 DPC count: 14160 _________________________________________________________________________________________________________ CPU 1 Interrupt cycle time (s): 0.144841 CPU 1 ISR highest execution time (µs): 18.331901 CPU 1 ISR total execution time (s): 0.001415 CPU 1 ISR count: 808 CPU 1 DPC highest execution time (µs): 265.431844 CPU 1 DPC total execution time (s): 0.006157 CPU 1 DPC count: 521 _________________________________________________________________________________________________________ CPU 2 Interrupt cycle time (s): 0.050883 CPU 2 ISR highest execution time (µs): 14.227663 CPU 2 ISR total execution time (s): 0.000252 CPU 2 ISR count: 113 CPU 2 DPC highest execution time (µs): 50.796105 CPU 2 DPC total execution time (s): 0.000961 CPU 2 DPC count: 71 _________________________________________________________________________________________________________ CPU 3 Interrupt cycle time (s): 0.052558 CPU 3 ISR highest execution time (µs): 9.446449 CPU 3 ISR total execution time (s): 0.000941 CPU 3 ISR count: 919 CPU 3 DPC highest execution time (µs): 56.669530 CPU 3 DPC total execution time (s): 0.001166 CPU 3 DPC count: 89
