Hy #172771 Info,
(1) ------------------------------------------
i know what's a mircokernel and the motivation
to develop one. I just changed the point of
view and tried to find the the practical impact
(or let's say) the advantages for the user of
a MC system like the new Mac-OS.
You may sit in front of your favourate GUI and
may say to yourself: "Great, while i am waiting
for the completion of the invoked request, the call may run through a proper OS-design"
This idea is not beeing meant to be cynical, but
i like to point out, that there exist a more
pragmatic view of this topic. The design issue
is only fascinating the tech people, but does not
offer a profit for a real use-case.
Another point is the fact, that today's
monolythic systems performed some architectual
improvements like kernel modules or the
fantastic STREAMS architecture (oh i really
like this!!)
(2) -----------------------------------------------
OK, FreeBSD is also very portable, but it is also
a monolythic kernel design, like LINUX.
(is FreeBSD also available on Mainframes ??)
But do not assume, that Mach3 gains the
protability of FreeBSD !! At last, please only
count real distributions not possible hacks !!
(3)--------------------------------------------
Please be more concrete. On Mac-X almost everybody use the BSD personality. There does not exist any other personality, so they spent
their time in emulation of a BSD interface.
This cause a performance loss and nobody
comforts me with the idea, that i could use
a actually not existing personality or any
feature, that i do not need !!
Ok, your argument with QNX is good, QNX may
be (or is) a proper solution for real-time
environments or embedded systems.
But the internet-applications, desktops systems
or middleware environments are the focus
of our discussion here, and this is Apples
focus use-case for their new OS !!!
(xx) ------------------------------------------
Please also take a look into Hubbards paper.
He pointed out the advantages of the Mac-X OS
and put focus on the GUI and the UNIX layer.
Hey and i said, why should i carry out the
burden of a performance loss, they could have
also use LINUX or FreeBSD instead of this
hydrocephalus.
