Effect of org.knime.core.maxThreads parameter

According to KNIME Help, this parameter “Sets the maximum number of threads that KNIME is using for executing nodes”. However, it does not seem to have much of an effect. I ran a workflow first with maxThreads = 8 and then with maxThreads = 2. In both cases all four CPU cores were running at 100%, no other processes were using CPU at the time. What would be the expected behaviour?

It depends a bit on which nodes you are using, as not all nodes necessarily respect this setting: A concern about number of core usage by KNIME during a Workflow execution.
