I prefer bogocity. Bogocity is near Robocity.

From what I understand this has nothing to do with IBM.
When they are ready, they'll pipe up. I could swear it was mentioned

On z/OS and VM, sure. The Linux version doesn't have any concept of
channel-attached drives, and the TSM people don't care to change that.

There is one big difference. Linux uses all available memory as a global
buffer. Buffers in z/OS are more localized to the job or device. The Linux
global buffering makes it difficult to impossible to find a point at which you
can be sure that what is on disk is the latest consistent data.

Wouldn't be the Linux bogomips a good comparison parameter, since
it comes in all Linux flavors?
As the name indicates, the "bogus" bogomips rating is a very good
indicator for comparing CPU performance. See this HowTo document for
details: http://tldp.org/HOWTO/html_single/BogoMips/

No. The bogomips number is determined by the result of a short timing
loop, which is directly dependent on how much CPU is available to that
specific virtual machine at the time it executes
