Running RTLinux-V3.0 Kernel 2.2.17 on the TB486 allows stable hard realtime operation. The system shows:
- 15 microseconds worst case jitter
- 10 microseconds event resolution
- 17 nanoseconds timer resolution
- 6 microseconds interrupt response time
These results are from a system running at a load average between 25 and 30, with multiple active interrupt sources.
