    <p>When the OS executes threads, it runs each thread for a certain period of time (say 10-20ms), then saves the state of the thread, and looks for other threads to run.</p> <p>Now, despite what you might think from looking at the CPU Utilization graph, the OS is actually running a lot more threads than those from your program. There are threads running UI loops, threads waiting on I/O, threads running background services, etc. Most of the threads spend most of their time blocked waiting on something.</p> <p>The reason why I'm talking about this is to explain that from OS's point of view, the situation is more complex than it might look. There are a whole bunch of threads doing a whole bunch of things, and the OS is attempting to switch between them. Suppose that you wanted to implement a heuristic that if a thread used up its entire quantum the last time, then the OS will make an effort to schedule it to the same core. The OS needs to track and take into account more information, and the success of the optimization may depend on a lot of hard-to-predict factors.</p> <p>In addition, the benefit of affinitizing a thread to a core are often negligible in practice, so OSes don't attempt to do it automatically. Instead, they expose a feature that allows the developer to explicitly say that a particular thread should be affinitized to a core, and then the OS will respect the decision.</p> <p>That seems like a reasonable trade-off: if your thread performs better when affinitized to a core, just ask the OS to do that. But, the OS won't bother attempting to figure it out for you.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
