In this
business we all need to know how to say I don't know and you taught
me
something as things change too fast to have our feet in concrete.
Lionel is right ... I say it all the time. Maybe I don't know, but
fortunately the members of this list are more than willing to share
their knowledge

Same for mainframe CPU as far as I know, which is one of the reasons
why we don't use the MIPS to rate the speed of a processor. Like what
is my MIPS rate when we have zero-cycle instructions?
Other way around. Modern processors are in instructions per clock. On
raw CPU power it doesn't just beat the mainframe - it steamrollers them.
Your I/O bus is typically PCI however so you are limited to about
100Mbytes/second I/O throughput in the real world.
I would regard 100Mb/sec as a

I would regard 100Mb/sec as a peak (instantaneous) transfer rate. Throughput will
be only a
fraction of that. On some tests
Lets take a real world benchmark. On $2000 of PC I can recompile the
entire Linux kernel in 3 minutes, and the entirity of XFree86 in 30. I
can saturate multiple 100Mbit links with web traffic. I can encode video
in real time to mpeg and burn it to VideoCD as I go. I can render
1024x768 3D

Vendor provided comparisons between its own products. Comparisons by
Ford between Ford cards don't tell you anything about whether its a
Porsche or Bicycle equivalent. And *no* credible mainstream computing
journalist will trust a vendor provided benchmark. They've seen enough
such material,
We actually disclosed all the internal results on the testing to date with
zSeries. It is available on our Website in response to the recent articles
off linuxworld.com.
It is a tremendous effort I can tell you to do Benchmarking with large mail
(millions of users) environments, all the so

Although
there seem to be lots of power users about, that's because they inhabit similar
places. A few
thousand or a few tens of thousands at most - compared

All I can say is I am disappointed that the editors would publish his rant

remember seeing
that particular bit of nonsense before, but if anyone else does, I'd
appreciate a pointer.
On to making this beast work, now.
