SGI and IRIX German technology website Heise.de reports that SGI will completely abandon its MIPS processor architecture, including its operating system Irix, in favour of Linux-powered Itanium workstations. SGI used MIPS and Irix in its products for almost 20 years, and with this switch to Intel, yet another major (historically speaking, that is) company abandons its architecture for the more common Intel one.

IRIX xfs produces the lowest I/O Wait time on Linux Distros than any of ext2/3 or Reiserfs or Reiser4.

I've tried it on Mandriva 2006 with all available kind of file systems

with xfs: copying concurrently 4 folders each with 500MB that includes small and large amount of files took 10% of CPU
and thus I was able to start other programs and use them

while on all other linux file systems it made the CPU at 100% and almost froze the system

I have confirmed this behavior on all distros

Then I did a very demanding test to see xfs power:
1. copy CDROM to disk
2. copy 12 instances of the previous folder internally to 12 different locations at the same time
3. transfer 17 GB over gigabit ethernet
4. open openoffice2 and opera9 and mozilla firefox1.5.0.2 at the same time
5. Run glxgears to obtain maximum GPU usage

and CPU was at 50% onlyyyyyyy.
Of course I have tried all kind of kernel updates (20 of them) to execlude the kernel as the source of high I/O wait times on linux with ext3/reiserfs.
I also have tested JFS of IMB AIX 5L to see how good it is, but it didn't hold a candle to xfs though was better than both ext3 and ReiserFS.

So this showed me that what we really need is not just another Unix but just an old linux with proper file system and device drivers will make the distro rock, and maybe then will linux gain serious footsteps towards market share. And thus SGI decision is perfect for them and for us.
