I did not have a machine to test at the meeting today. We have 
scheduled a hands on demo for Wednesday, March 14. Our rep
will prepare a system with the latest operating system for
this demo. Apparently the version of AIX currently installed is a demo
version only. It operates slower than the release version
will because of debugging traps, etc.

I have received the drystone 2.1 demo and the xfroot demo. Did not
have a chance to try the x benchmark yet. I tried the drystone
on an RT 6150 AIX 2.1.2 (~2100 drystones), a Sun 3 [150?] 4.0.3
(~2800 drystones), a Vax [11/750?] BSD 4.3 (~1600 drystones), 
and Macintosh II A/UX 1.01 (~2900 drystones). The RISC/6000 is
advertised to run ~45K drystones.

Please send additional benchmarks or tell me where I can find them.
I've heard about the Byte Unix benchmarks. I would like to find
some kind of SCSI and some ethernet benchmark as well. Also,
IBM's results are in Mips and Mflops. Does anybody have the calculations
to convert the drystones to this figure or have an actual benchmark?

The RISC/6000 will dosread a 720K or 1.44m 3.5" floppy
