Amiga & AROS It's really been an Amiga week, hasn't it? As such, it seems only fitting to close this week off with some seriously epic news from the Amiga community. As most of you will know, Hyperion and Amiga, Inc. have been embroiled in a tough legal battle over the distribution and development rights of the AmigaOS, and all its associated trademarks. The epic news is that this situation is now completely and utterly resolved.

I have long wondered how much the Amiga-like operating systems would slow down once they had to do all the things that modern operating systems had to do.

Memory protection slows down a computer a LOT if it has to process a lot of page faults. That's why I have higher hopes for AmigaOS 3.x than 4.x. Little or no MMU support and a flat memory model. That's what it takes to be a fast OS.

If you don't believe me, try running AmigaOS 4.0 for classics and see if OS 4 running on a 150 MHz PowerPC is any faster than a 50 MHz 68060. I'll give you a hint: It isn't. The 68060 will win most of the time because it takes fewer and smaller opcodes to do the same programming and the MMU support costs processor power.

I see I'm starting to repeat myself so I'll just leave you with these thoughts.

The lack of memory protection makes the operating system simpler and encourages coding applications with high elegance in mind.

I have hopes in AmigaOS-like operating systems.

Indeed, that's one criticism of Amiga that I've never really gotten. The lack of protected memory has always struck me as more of an advantage than a disadvantage, at least for the heavily interactive sort of stuff that Amiga is used for. Yes, in a server context Memory protection can be crucial, but for single user system, proper coding and a good memory allocator WITHOUT "hard" protection make for a much better performing system.
