How to avoid hard pagefaults
If you have concluded that hard pagefaults are the cause of audio dropouts, you can do any of the following to resolve the problems:
Close down unnecessary applications which consume a lot of RAM
Close down unnecessary service applications which consume a lot of RAM (the Search Indexer service is notorious)
Increase the amount of RAM in your system
Increase the working set of the audio application, only an option if you are the author of the software.
Make sure audio data is paged-in (resident). Pages of memory are swapped out based on their use counts. If you use Windows for live playing, do a silent run of your software synthesizer. After changing patch on a sampler, touch all keys so that all memory it uses is paged-in to avoid embarrasing scenes.
Disable the pagefile altogether. You can disable the pagefile by right-clicking My Computer and selecting Advanced System Settings->Advanced->Performance Settings->Advanced->Virtual memory->Change. Note that if you have no pagefile, the system can run out of memory if not enough memory is available. Also the system will no longer create crash dump files in case of a system crash.

bedeutet (das wichtigste):
- keine Programme nebenher laufen lassen, die viel RAM brauchen
- unnötige Servicedienste deaktivieren (zb. den Windows Search Dienst über Dienste deaktivieren)
- dem System mehr RAM spendieren
- Virtuellen Speicher bei genug RAM deaktivieren
