1. Any permanent mark to which other levels may be referred.
such as:
(a) A horizontal mark at the water's edge with reference
to which the height of tides and floods may be
measured.
(b) a surveyer's mark on a permanent object of
predetermined position and elevation used as a
reference point.
[Webster 1913 Suppl. + WordNet 1.5]
2. something serving as a standard by which related items may
be judged; as, his painting sets the benchmark of quality.
[PJC + WordNet 1.5]
3. a test or series of tests designed to compare the
qualities or performance of different devices of the same
type. Certain sets of computer programs are much used as
benchmarks for comparing the performance of different
computers, especially by comparing the time it takes to
complete a test.

A standard program or set of programs which can be
run on different computers to give an inaccurate measure of
their performance.
"In the computer industry, there are three kinds of lies:
lies, damn lies, and benchmarks."
A benchmark may attempt to indicate the overall power of a
system by including a "typical" mixture of programs or it may
attempt to measure more specific aspects of performance, like
graphics, I/O or computation (integer or floating-point).
Others measure specific tasks like rendering polygons,
reading and writing files or performing operations on
matrices. The most useful kind of benchmark is one which is
tailored to a user's own typical tasks. While no one
benchmark can fully characterise overall system performance,
the results of a variety of realistic benchmarks can give
valuable insight into expected real performance.
Benchmarks should be carefully interpreted, you should know
exactly which benchmark was run (name, version); exactly what
configuration was it run on (CPU, memory, compiler options,
single user/multi-user, peripherals, network); how does the
benchmark relate to your workload?
Well-known benchmarks include Whetstone, Dhrystone,
Rhealstone (see h), the Gabriel benchmarks for Lisp,
the SPECmark suite, and LINPACK.
