Friedman).2. often bench mark A surveyor's mark made on a stationary object of previously determined position and elevation and used as a reference point, as in geologic surveys or tidal observations.tr.v. bench·marked, bench·mark·ing, bench·marks To measure (a rival's product) according to specified standards in order to compare it with and improve one's own product.
[From the use of the surveyor's mark as a place to insert an angle iron that serves as a bench, or level surface, for the support for a leveling rod.]benchmark (ˈbɛntʃˌmɑːk) n1. (Surveying) a mark on a stone post or other permanent feature, at a point whose exact elevation and position is known: used as a reference point in surveying.

(as modifier): a benchmark test. vbto measure or test against a benchmark: the firm benchmarked its pay against that in industry. bench′ mark`
n. 1. a mark of known or assumed elevation from which other elevations may be established. Abbr.: BM 2. benchmark. bench′mark` or bench′ mark`
n. a standard or reference by which others can be measured or judged.

benchmark[′bench‚märk] (engineering) A relatively permanent natural or artificial object bearing a marked point whose elevation above or below an adopted datum—for example, sea level—is known. Abbreviated BM. (industrial engineering) A standard of measurement possessing sufficient identifiable characteristics common to the individual units of a population to facilitate economical and efficient comparison of attributes for units selected from a sample. (science and technology) A reference value against which a measurement or a series of measurements may be compared. BenchmarkA permanent reference mark, fixed to a building or to the ground, whose height above a standard datum level has been accurately determined by survey.benchmark (benchmark)A standard program or set of programs which can berun on different computers to give an inaccurate measure oftheir 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 asystem by including a "typical" mixture of programs or it mayattempt to measure more specific aspects of performance, likegraphics, I/O or computation (integer or floating-point).Others measure specific tasks like rendering polygons,reading and writing files or performing operations onmatrices. The most useful kind of benchmark is one which istailored to a user's own typical tasks. While no onebenchmark can fully characterise overall system performance,the results of a variety of realistic benchmarks can givevaluable insight into expected real performance.
Benchmarks should be carefully interpreted, you should knowexactly which benchmark was run (name, version); exactly whatconfiguration was it run on (CPU, memory, compiler options,single user/multi-user, peripherals, network); how does thebenchmark relate to your workload?
Well-known benchmarks include Whetstone, Dhrystone,Rhealstone (see h), the Gabriel benchmarks for Lisp,the SPECmark suite, and LINPACK.

Tennessee BenchWeb.benchmarkA performance test of hardware and/or software. There are various programs that very accurately test the raw power of a single machine, the interaction in a single client/server system (one server/multiple clients) and the transactions per second in a transaction processing system. However, it is next to impossible to benchmark the performance of an entire enterprise network with a great degree of accuracy.
Benchmarks may change their rating scale with new releases of the software. Thus, the same version of the test must often be run to compare results. See PC Magazine benchmarks, BAPCo, ECperf, Linpack, Dhrystone, Whetstone, Khornerstone, SPEC, GPC and RAMP-C.benchmark
benchmark (bench′mark″) 1. A criterion of quality or service in health care, usually expressed as a measurable standard. 2. A reference standard or basis for comparison that serves as a definition of a norm. Benchmark
BenchmarkThe performance of a predetermined set of securities, used for comparison purposes. Such sets may be based on published indexes or may be customized to suit an investment strategy.BenchmarkA standard against which a security's performance is compared. A benchmark is usually an index of securities of the same or similar class. Stocks are usually compared against stocks; bonds against bonds, etc. Another type of benchmark considers securities according to industry: a telecommunications stock may be compared to other telecommunications stocks. Likewise, mid-cap securities may be benchmarked against other mid-cap securities. Some indices, such as the Dow Jones Industrial Average and the S&P 500, are considered to be benchmarks for the wider economy.benchmark A standard by which something is measured. For example, bond yields are generally compared to benchmark yields on U.S. Treasury securities of similar maturity. Mutual fund performance is often compared to changes in the Standard & Poor's 500 Stock Index.Benchmark.An investment benchmark is a standard against which the performance of an individual security or group of securities is measured. For example, the average annual performance of a class of securities over time is a benchmark against which current performance of members of that class and the class itself is measured. When the benchmark is an index tracking a specific segment of the market, the changing value of the index not only measures the strength or weakness of its segment but is the standard against which the performance of individual investments within the segment are measured. For example, the Standard & Poor's 500 Index (S&P 500) and the Dow Jones Industrial Average (DJIA) are the most widely followed benchmarks, or indicators, of the US market for large-company stocks and the funds that invest in those stocks. There are other indexes that serve as benchmarks for both broader and narrower segments of the US equities markets, of international markets, and of other types of investments such as bonds, mutual funds, and commodities. Individual investors and financial professionals often gauge their market expectations and judge the performance of individual investments or market sectors against the appropriate benchmarks. In a somewhat different way, the changing yield on the 10-year US Treasury bond is considered a benchmark of investor attitudes. For example, a lower yield is an indication that investors are putting money into bonds, driving up the price, possibly because they expect stock prices to drop. Conversely, a higher yield indicates investors are putting their money elsewhere. Originally the term benchmark was a surveyor's mark indicating a specific height above sea level. benchmarkA permanent reference mark,usually set in concrete or iron and used to establish the elevation above sea level or certain corners in a surveying system. All other measurements in the area should be checked for accuracy relative to the nearest benchmark, preferably against several nearby benchmarks to establish redundancy. BENCHMARK
