About multitasking, what's best : AmigaOS, Linux, or Winblows XP ?

[ptek]

Hello,

Multitasking seems to be a hot matter these days.

For who use a lot Linux and Winblows (XP, 2000, NT) could please tell us what OS does best multitasking and why. Amiga still does it better than the others ?

And I was forgetting MacOS ...

Please justify your claims

[ptek]

So, the Amiga is better at multitasking than Linux ?

[ptek]

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 ?

[ptek]

@Speelgoedmannetje,

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

[ptek]

@Piru

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

[ptek]

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

 

:lol:

@chsedge

4. AmigaOS

Very limited and aged round robin scheduler. Only pre-Windows 95 and classic Mac OS are worse.

So, from you answer we may conclude that the http://en.wikipedia.org/wiki/Amiga
entry saying that the Amiga has pre-emptive multitasking is wrong ?

[ptek]

OK I was not familiar with the round robin thing
tnx Piru

@Agafaster

try multitasking in a graphical environment, in a low power (by modern standards) system:
AmigaOS: A1200 030 at 25MHz with 8MB ram OS3 (any of em!)
Linux: same setup, but one of the m68k builds, I tried BSD (couldnt get X working) and debian 2.something m68k build.

you will find that linux is dog slow even just running X! ok, thats cheating a smidge, cos I was trying to use X on AGA, but the point, I believe, is made.

I don't think the Linux slow performance in these case matters for the multitasking question ... The slow performance seems due to hardware limitation (linux makes use of virtual memory) and as we know the Amiga HW (HD access - maybe with a real SCSI HD would be better - , memory BUS among and others things) are really outdated, so even the multitasking as Linux is pre-emptive and not round robin, in the Amiga hardware the system crawls due to HD limitations (like trying using the AGA achitecture on a X based chunky display)
