See section 4.14 in AOB Computer Transports version 0.3 for more details.

Research on Operating System Jitter shows significant dependencies for performance (in massively paralleled computing systems) and for effective realtime processing. OS jitter refers to timing errors caused by OS for scheduled process / thread events. Key to reducing such jitter is eliminating OS bloat, an unfortunate Windows trait. For technically minded, here's useful research material from IBM:

1. Operating System Jitter
   
2. Identifying Jitter Sources

Feedback needed.
