Questions tagged [chaos]

Anything related to chaotic systems or chaos theory. Chaotic systems are systems that are extremely sensitive to initial conditions (e.g. round-off error in data stored digitally) thus leading to the impossibility of predicting their long-term evolution. The tag is mostly relevant to cases where algorithms show chaotic behavior.

Is there a way to easily make a specific directory slow for a unit test?

My goal is to run a test against a file system which is intentionally slow, to test performance metrics in chaotic storage scenarios. In the same sense that there are ways to limit memory and cpu with cgroups in containers, i've considered wether…
