Learn how to read Sysbench test results


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.

Test Name total_time per_request_avg per_request_p95 events_rate
Multithreaded 30.00 s 7.27 ms 14.21 ms 549.94 ops/sec
Single Thread 30.00 s 1.79 ms 1.89 ms 558.32 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.
Sysbench fileio tests are run in synchronous mode, all operations are buffered. All tests are run with a number of threads that matches the number of vCPUs found in the instance with a minimum of 4.
