Hello Carsten,
please let me know which database version you are using and if the Analyzer message is labeled as 'info' or 'warning' or has no preceeding indicator at all.
We will probably change the message text somewhat. It originates from the early times of hyperthreading and multi core CPUs when using more logical CPUs than physical CPU cores could lead to a performance bottleneck - of course times have changed since...
