Benchmark performance test (eng. Benchmark ) - a control task necessary to determine the comparative characteristics of the performance of a computer system. Sometimes benchmarks are also programs that test the battery life of laptops and PDAs, the range of the wireless network, the bandwidth of data transmission channels, the amplitude-frequency response of the audio path, and other characteristics that are not directly related to performance.
Benchmarks are used to compare the performance of computers and are often a criterion for selecting a component of a particular manufacturer. In addition, the successful completion of a series of tests is evidence of the stability of the system in normal and overclocked modes.
The number of benchmarks is growing every day. Nevertheless, only a few dozen of them are generally recognized, and the performance ratings of those or other computer components are often based on the results of which.
Many computer games, due to their demands for hardware and the dependence of the speed of the game on the power of computers, are successfully used as benchmarks. Typically, the benchmarking of a computer in a game is as follows: a pre-recorded test demo is launched and the number of frames per second (FPS) is measured, which the system under test is capable of issuing. Test results in different resolutions and with different quality settings are entered into a table.
With great success, various tasks that are performed daily by users on a computer can be used to compare performance, for example:
Measuring the execution time of the same operation on the same source files, but on different computers, you can get a comparative performance characteristic.
Recently, benchmarking, that is, competition in the performance of computers in special tests, has become a special kind of virtual sport. Benchmarking was widely adopted after the appearance of the test results system FutureMark Online Result Browser. The main test with which overclockers and just owners of powerful computers compete with each other is FutureMark 3DMark. In second place in popularity in the so-called. Benchers worth the test Aquamark. The personalities (or network nicknames) of the authors of the most impressive records in these tests become relatively famous in the circle of the same benchers (benchmarkers).
Benchmarking as a kind of virtual sport has the same features as eSports: dividing into interest groups (owners of a video card, processor, etc.) and cheating (deception of the results recording system).
Test phoronix-test-suite. This is a set of modern tests that allow to evaluate the system performance by several parameters:
Iozone hard drive test. The result of this test is data on the speed of writing, rewriting and reading files of various sizes with different block sizes.
Usually they calculate the average value of the speed of writing, reading, random writing and random reading of a file of 8 Gb size with a block size of 1 Mb. According to the data obtained, it is easy to compare the performance of the disks of the studied servers.
