Interbench is an interactivity benchmark written by Con Kolivas. Interbench is primarily intended to test out the system kernel and its CPU scheduler while running a simulated test with a given simulated load in the background. Each benchmark / load is run for 60 seconds per test.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark interbench.

Use with caution this test profile is currently marked Deprecated.

Based on data, the selected test / test configuration (Interbench 0.31 - Benchmark: Gaming - Background Load: Read) has an average run-time of 16 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
