SYSTEM INFORMATION
Computer name: ---------
OS version: Windows 7 Service Pack 1, 6.1, build: 7601 (x64)
Hardware: All Series, ASUS, ASUSTeK COMPUTER INC., Z87-K
CPU: GenuineIntel Intel(R) Core™ i7-4770 CPU @ 3.40GHz
Logical processors: 8
Processor groups: 1
RAM: 32702 MB total
\
CPU SPEED
Reported CPU speed: 3468,0 MHz
Measured CPU speed: 398,0 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.
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): 163,272199
Average measured interrupt to process latency (µs): 2,173989
Highest measured interrupt to DPC latency (µs): 161,500711
Average measured interrupt to DPC latency (µs): 0,767341
\
REPORTED ISRs

Highest reported total ISR routine time (%): 0,000454
Driver with highest ISR total time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation
Total time spent in ISRs (%) 0,00080
ISR count (execution time <250 µs): 30143
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): 132,284025
Driver with highest DPC routine execution time: Wdf01000.sys - Kernelmodustreiber-Frameworklaufzeit, Microsoft Corporation
Highest reported total DPC routine time (%): 0,010747
Driver with highest DPC total execution time: iusb3xhc.sys - Intel(R) USB 3.0 eXtensible Host Controller Driver, Intel Corporation
Total time spent in DPCs (%) 0,028374
DPC count (execution time <250 µs): 478991
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.
Process with highest pagefault count: vsserv.exe
Total number of hard pagefaults 216
Hard pagefault count of hardest hit process: 109
Highest hard pagefault resolution time (µs): 1234,352941
Total time spent in hard pagefaults (%): 0,001240
Number of processes hit: 10

Die Ressourcen-Fresser sind definitiv die HOFA-PlugIns. Wenn ich den VST3-Ordner leere, im Projekt folglich keine mehr verwendet werden, steht die AVG-Auslastung bei 25%.
Ich habe auch das Oversampling für einen Teil der Plug-Ins ausgeschaltet, damit erreiche ich auch eine Verbesserung, zwar noch nicht den Zielwert von 75%, allerdings doch soviel, dass ich flüssig arbeiten kann.
Welche Erfahrungen habt ihr mit den ASIO-Einstellungen? Wie stellt man die am sinnvollsten ein?
