MkLinux vs LinuxPPC (speed)

Post by Edmund Pira » Mon, 28 Dec 1998 04:00:00



I have just started playing around with Linux on Mac and from installing
both MkLinux and LinuxPPC I have found the following:

- LinuxPPC seems to be much faster (specially during the install phase).
Has anyone else noticed this? If this is really the case it would not bode
well for the upcoming MacOS X with the Mach Kernel (as a developer and
user I am looking forward to significant speed gains in OSX compared to a
still mostly emulated OS).

- LinuxPPC seems much more stable (MkLinux would die quite often, I have
not been able to bring down LinuxPPC 4 lite yet). This would seem to go
contrary to Apples involvement in MkLinux.

- Neither use any acceleration features of the ATI graphic chip. Anyone
know is there is a way to "wake" Linux up to this?

All these "observations" are from a Powerbook G3 Series (250) machine with
96 MB of RAM and an external Jazz drive.

I actually have the same fears as you do. I am also an apple developer and and
found LinuxPPC to be faster, more stable and better supported than mkLinux.
However, I thought OSX was supposed to be aimed not at the home user, but at
the enterprise markets and business administration.
    I heard rumors that mk has recently been dismantled and scattered to the
four winds.....But, this is just a rumor.......

    Have you been able to get you hands on  Rhapsody DR2? After joining the
ADC I was informed that, because of licensing issues, we would not receive a
copy of the CD set.....Could I get a copy from you if you do, in fact, have a
set? Thanks in advance!
                                        Sincerely,

Yes, it is true that LinuxPPC is faster than Mach Linux. Yes, I have
noted
this. HOWEVER, this is not due to  the theoretical difference.
In theory, the speed difference will be around the 1-3% mark. Educated
guess.
In other words: you don't notice it. The advantages of Mach outweigh
this, when they are taken seriously.
What is happening in the Linux community, is that LinuxPPC is getting
the better support. Therefore it is more tuned, more stable, etc. etc.

This is very dependant on your machine. I have a 7600, which was
supported
from Mach DR2 (about), and has ripe drivers. This comes down to: it is
as
stable as LinuxPPC.
I guess your Powerbook was only recently added.
O, and I crashed LinuxPPC. Several times (although admittetly same bug).

Yup. Dive in the sources and start coding.

I can check on this here, but you know, Apple licensing terms don't allow
this. All you have to do is to ask them to send you another one (one of
the Rhapsody CDs they had sent me got "bent" in the mail and they sent me
a replacement pretty quickly).

Rhapsody on my machine kinda behaved like MkLinux. But it had more draw errors.

Where did you get that information that Applix is releasing a version of
their office suite for linuxppc?  I was going to buy a new laptop, and
really wanted to get one of the later G3 Powerbooks, but not having a
linux based office suite for the ppc hardware, was stimulating me to
look at the intel hardware market instead :-(

Uh...except that you can run MacOS under Rhapsody if you've got enough
ram... Big difference if you ask me!

You are refering to the Blue Box (tm) I suppose.

You might want to read http://www.sheepshaver.com.
Soon the MacOS will run on LinuxPPC (and probably MkLinux).

What's the difference between RealSoonNow and RightNow?  

[hint: RealSoonNow often changes its name to VaporWare]

I'll believe SheepShaver the day I have it installed and working on my computer.

Yup!

Yeah, but BlueBox runs today...big difference for me...  :)

What is the latest release date for SheepSaver, BTW?
