Background Daemons

Types of Deamon

Besides the main Benchmark NumIO ensembles also spawns some daemons to create background noise. These are used to create a more realistic environment for to run the benchmark in. There are a few premade daemons:

Chatty

This is a daemon that creates a lot of network usage. Usually a single program not use this much network.

It is still useful to simulate a high combined network load.

Disk

This daemon creates a lot of disk I/O. It can be used to simulate something like a grep task.

CPU

This daemon creates a lot of load on the CPU. You can use it to simulate a compute task or similar.

Daemons In Advanced Mode

In advanced mode you will find the custom subcommand. This command lets you decide how many of the different daemons you want to run in the background. Use this feature to simulate a workload that is not standardized, but realistic for your system.
