Hello,

The project looks very interesting. However I have a question. What is in AmigaOS which is worth saving when compared to Linux, Windows, BSD, etc? I was going to start a thread on this but I think it does fit here.

I understand that the structure of all these Operating Systems is different. So what does AmigaOS (or any of its variants) have as a pro when compared to the other Operating Systems, and will these features be included in the new OS?

Regards,
Sim085



Pfft!!!

Excelent Multi tasking.

AmigaOS scheduler is rather lame. Any busy higher priority task will block lower priority ones forever. Having tons of tasks results in exponential slowdown inside the scheduler (it uses linear list walking). There is no guaranteed fairness in the scheduler. Anything has a better scheduler these days.
Ehm, IIRC AmigaOS uses a Round Robin scheduler (the most basic pre-emptive scheduler), with which scheduling starvation does not exist.


This is quite an interesting read:
