Number of threads in Oracle XE 18c I just installed Oracle XE 18c ... In this page, they list the available features/resources. One of them is the use of two CPU threads ...

But, in practical terms, what does this mean?  Does this mean that only two queries can be executed concurrrently? or what?
From the Installation Guide ( here )


  Oracle Database XE limits itself automatically to two cores for processing. For example, on a computer with 2 dual-core CPUs (four cores), if a large number of database clients try to simultaneously execute CPU-intensive queries, then Oracle Database XE will process the queries at the rate of just two cores even if more CPU capacity is available. 


I would image "large number" means ">2".
