_________________________________________________________________________________________________________ CONCLUSION _________________________________________________________________________________________________________ Your system appears to be suitable for handling real-time audio and other tasks without dropouts. LatencyMon has been analyzing your system for 0:04:48 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: FRACTAL-PC OS version: Windows 8 , 6.2, build: 9200 (x64) Hardware: ASUSTeK Computer INC., Crosshair IV Formula CPU: AuthenticAMD AMD Phenom(tm) II X6 1090T Processor Logical processors: 6 Processor groups: 1 RAM: 12286 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 3725 MHz Measured CPU speed: 18 MHz (approx.) 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): 414,577830 Average measured interrupt to process latency (µs): 9,168862 Highest measured interrupt to DPC latency (µs): 396,000050 Average measured interrupt to DPC latency (µs): 3,294938 _________________________________________________________________________________________________________ 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): 54,085638 Driver with highest ISR routine execution time: SCSIPORT.SYS - SCSI Port Driver, Microsoft Corporation Highest reported total ISR routine time (%): 0,002778 Driver with highest ISR total time: USBPORT.SYS - USB 1.1 2.0 Port-driver, Microsoft Corporation Total time spent in ISRs (%) 0,007282 ISR count (execution time <250 µs): 21496 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): 461,056913 Driver with highest DPC routine execution time: tcpip.sys - TCP/IP-driver, Microsoft Corporation Highest reported total DPC routine time (%): 0,138077 Driver with highest DPC total execution time: rspLLL64.sys - Resplendence Latency Monitoring and Auxiliary Kernel Library, Resplendence Software Projects Sp.

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.
