    1. COThere's a way to this on Windows for sure. I'm not sure about GCC on Linux though. However, I'm not sure you want to declare read memory as uncachable. Although you won't pollute the cache, you (might) be paying the full memory latency for each access.

    2. COI agree that it may not improve the performance. But I would be nice to know how to use this feature.

    3. COThere is no way to disable the cpu cache. Nor would you ever want to, it will make it horribly slow. Uncached memory reads easily take more than a hundred cycles.

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.
