Yes it is multi-tasking but its not "true" multi-tasking.

Well by that definition AmigaOS isn't true multitasking either.

In a way your right but I'm sure you would agree that the Amiga will be far more efficient at it. And as I mentioned before try formating more then one drive at the same time on a PC
Amiga 2000HD Indivision ECS
Amiga 4000D towerised OS 3.1 and 3.9 on CF cards
Indivision AGA, Mediator 4000
Video Toaster 4000 Flyer v4.3 Millenium.
202gig of video drive space & 5gig audio.

So what? How often do you actually do that? I don't exactly think that's a good test of how good an OS is at multitasking.

Its merely one example.  And why isn't a good test?

A4000T. Phase5 PPC604e-233mhz/060-66mhz. Mediator, Z3 Fastlane, Voodoo5, Delfina, X-Surf, AD516, Peggy Plus.

Collection:

I disagree.
It shows how it manages it's resources.

I'm not sure how much of this is done by the Newtek cards but still running a video project in the switcher involves running a ton of processes at the same time. The Amiga does just fine doing that. There is no way a windows machine with as little ram and CPU speed could even dream of doing that even today.

So I ask :

Is there a perfect multitasking machine on this planet :) ?

The multitask theory seems well defined, but is there a perfect implementation of it ? Or the current implementations on Linux and Winblows NT based get close to it, but loses from unefficient resource managment/memory swap effects ?

As I can read on
http://en.wikipedia.org/wiki/Amiga
the Amiga has pre-emptive multitasking ... Is this wikipedia entry wrong ?

Is the pre-emptive multitasking the perfect multitasking ?

Onions have layers ...

Apart from programs wich are programmed by me, there is no perfect program in the world so there's not a perfect implementation of multitasking either.

No it isn't wrong.

No.
It's just multitasking. Co-operative multitasking can rather be called program switching rather than multitasking.

I don't see much difference from technical point of view.

And as I said already, it's more the sucky floppy controller and it being ISA HW (cpu polled crap), not software.

I have to disagree really. Assuming you had the equal functionality in the software and hardware, I see no reason why equally specced windows box couldn't handle it. Windows itself requires larger memory footprint, but other than that it should be fine.

But why would you want to limit your video editing to something like the old amiga solutions? Or why would you deliberately want to run something like video editing on 10-15 year old PC?

@Speelgoedmannetje,

But pre-emptive is better than co-operative multitasking, right ?

As far i understood, tonyvdb was refering to HD drive formatting, not floppy.

Well, you can't find any co-operative multitasking OSes around anymore, does that answer your question? :-)

Definately. As I stated, co-operative multitasking can hardly/not be called multitasking.
But pre-emptive multitasking comes also in multiple flavours, like Round Robin.

I have never seen ANY problems with that, the performance is just fine. Formatting HDD is hardly CPU bound, the CPU usage is 1-2% when formatting anyway.

No it's not fine. Windows is tied and glued together, not designed with these features. I have had too many problems with Windows to call it fine.
