Benchmark
国内的网站上搜不到合适的解释，百度百科也没说清楚，请教了一下wikipedia，得出以下解释：
In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. The term 'benchmark' is also mostly utilized for the purposes of elaborately-designed benchmarking programs themselves.
Benchmarking is usually associated with assessing performance characteristics of computer hardware, for example, the floating point operation performance of a CPU, but there are circumstances when the technique is also applicable to software. Software benchmarks are, for example, run against compilers or database management systems.
Benchmarks provide a method of comparing the performance of various subsystems across different chip/system architectures.
Test suites are a type of system intended to assess the correctness of software.
