- Depends on what you think about, though. For real-time applications,
- this saving of memory and/or CPU is vital.

- I remember having hacked a C-code down to pieces. Without being
- much proud of the result which was unreadable, even well documented,
- but we were quite satisfied to see the thing working in real-time.
- We were talking about I/O rates of about 170 Mbits/sec...
- Without such skills and knowledge of our processors, we would have
- been waiting for next generation supercomputers, paid them huge
- amounts of money, and used maybe 50% of their actual capabilities.
