The cpu test is one of the most simple benchmarks in SysBench. In this mode each request consists in calculation of prime numbers up to a value specified by the --cpu-max-primes option. All calculations are performed using 64-bit integers. Each thread executes the requests concurrently until either the total number of requests or the total execution time exceed the limits specified with the common command line options.
|Multithreaded||30.00 s||6.37 ms||11.87 ms||627.36 ops/sec|
|Single Thread||30.00 s||2.38 ms||2.61 ms||420.77 ops/sec|
This test mode can be used to produce various kinds of file I/O workloads. At the prepare stage SysBench creates a specified number of files with a specified total size, then at the run stage, each thread performs specified I/O operations on this set of files.
