Hi,
Has anyone measured the impact of LCM checking the server for conformity when it’s fully scripted? CPU/memory/IO
Can it impact negatively services running on the server or is it negligible?
It depends on what you’re having DSC do. You could write a custom resource that is very intensive. But in reality, most of what’s being done during a check is lightweight (reading registry keys and the like). Before rolling out DSC here, I started perfmon, ran Test-DscConfiguration for a sample configuration I had applied, and examined the results. It didn’t have much of an impact on the system at all.
