Hi there.
Yesterday I’ve updated my system to W8.1 64bit.
Cubase Pro 8.0.20 works really solid and rock stable (as said by Fabio Bartolini some thread ago).
I’ve done some tests with LatencyMon to see what happens in details about drivers, processes, etc.
Here there are my stats.
What do you technically think about this stats?
I see that “storport” and “usbport”, as seen in so many threads are causing hard page faults.
Actually I don’t have problems working with my system but I’d like to know if there’s a way to avoid this “issue”.
Thanks to all of you.
I paste you the log:
CONCLUSION
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for 0:30:53 (h:mm:ss) on all processors.

SYSTEM INFORMATION
Computer name: TOUCHCLAYSTUDIO
OS version: Windows 8 , 6.2, build: 9200 (x64)
Hardware: Gigabyte Technology Co., Ltd., Z77-DS3H
CPU: GenuineIntel Intel(R) Core™ i7-3770 CPU @ 3.40GHz
Logical processors: 8
Processor groups: 1
RAM: 16346 MB total
\
CPU SPEED
Reported CPU speed: 3430,0 MHz
Measured CPU speed: 2399,0 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.

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): 142,098799
Average measured interrupt to process latency (µs): 4,900906
Highest measured interrupt to DPC latency (µs): 140,009111
Average measured interrupt to DPC latency (µs): 1,597127

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.

Total time spent in DPCs (%) 0,028130
DPC count (execution time <250 µs): 1103272
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 0
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: svchost.exe
Total number of hard pagefaults 41053
Hard pagefault count of hardest hit process: 33181
Highest hard pagefault resolution time (µs): 919398,982216
Total time spent in hard pagefaults (%): 0,481391
Number of processes hit: 15
