One of the useful things about interpreted languages like Python forprogramming, especially system administration, is that there is nodistinction between the source code and the executable program. Thismeans that you never have to play the exciting game of 'where's thesource, and for that matter the build instructions, and does it evenbuild with a modern compiler?'

(I once had the interesting assignment of converting a program writtenfor the V6 Unix version of C into something that would compile on a moreconventional C

Today I got curious about a simple question: was my iSCSI targetmachine actually running at its full potential read speed?

The machine exports individual disks to its clients, so measuringsingle disk performance wouldn't give me the answer. Summing up IOacross all the disks would have given me a number, but so would justgetting the network bandwidth utilization; if the machine was saturatingits gigabit link, it was clearly running as fast as it could.

There doesn't seem to be a program that will directly
