Uffff...if you have tried it then possibly you don't know how to set it
up. I have both the Mach kernel version of MkLinux DR2 with the PCI
patch and the monolithic MkLinux DR2 with PCI patch kernel running on a
spare Power Macintosh 7500 and it is quite acceptable.

Here are some example Linux benches on Pentiums first and then on HP900
from http://www.silkroad.com/linux-bm.html
I edited out the items that used IDE or EIDE drives as they are not
directly comparable to the PCI/SCSI combination on the Power Macintosh.
There are also many other systems listed on the these pages. You might
check them out if you are interested in Linux.

58. Pentium P5 90 Mhz 16 M RAM PCI SCSI-II 57.7 9.6
61. Pentium P5 90 Mhz 16 M RAM PCI SCSI 54.4 9.1
62. Pentium P5 90 Mhz 32 M RAM SCSI - 54.3 9.1
63. Pentium P5 90 Mhz 16 M RAM PCI SCSI-II 52.5 8.8
64. Pentium P5 90 Mhz 16 M RAM PCI SCSI-II 51.5 8.6
67. Pentium P5 75 Mhz 16 M RAM PCI SCSI-II 48.1 8.0
74. Pentium P5 60 Mhz 48 M RAM PCI SCSI-II 42.4 7.1

1. HP 9000 755 99 Mhz 64 M RAM SCSI-II 84.3 14.1
2. HP 9000 735 99 Mhz 80 M RAM SCSI-Wide 69.6 11.6
3. HP 9000 743i 64 Mhz 64 M RAM SCSI-II 53.3 8.9
4. HP 9000 720 50 Mhz 32 M RAM SCSI-II 49.9 8.3
5. HP 9000 715 50 Mhz 32 M RAM SCSI-II 28.6 4.8

My PM7500 has SCSI-II, PCI and 2 hard drives, a 1GB and a 3GB. The
mach-based version is comprised of three different AUX partitions on the
1GB drive. These are 100MB root, 32MB swap and 600MB usr. This is the
original disk. The monolithic version is on the 3GB drive. It comprises
4 partitions. These are a 200MB root, 32MB swap, 1000MB usr and 1000MB
local.

Also, note that these results are for a developer release of a
non-optimized OS. Meaning that currently, MkLinux is not-optimized for
the PCI machines and is still in development. Once the OS is released as
a reference version, I would expect results to improve. Also note the
difference in the mach-kernel version and the monolithic version.

I believe, whether unfounded or not, the once MkLinux is fully optimized
for the Power Macintosh/PCI combination and it has been available for a
few interations and become solid, that it will beat the intel version
without trouble. I further believe that benchmarks ran on a PPC604e
equipped machine will be much higher. I'd like to see stats for a
PPC604e/225 MHz machine!

1. PM7500/100 PPC601/100 Mhz 64 M RAM 512k Cache PCI SCSI-II
                60.7 10.11 //monolithic version
2. PM7500/100 PPC601/100 Mhz 64 M RAM 512k Cache PCI SCSI-II
                47.7 7.95 //mach-kernel version

Well, anyway, I do like standards and UNIX and NIX clones seem to be the
best for adhering to truly open standards. I personally prefer BSDI/OS
on a fast pentium box but that may change in 6 months. I'll have to see
what the status of the MkLinux community is at that time, especially
considering the faster processors that will be available soon.
