cpu
The cpu 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.
