Body
Andrei Alexandrescu made the good point in that you should measure your code (<a href="https://www.facebook.com/notes/facebook-engineering/three-optimization-tips-for-c/10151361643253920" rel="nofollow">https://www.facebook.com/notes/facebook-engineering/three-optimization-tips-for-c/10151361643253920</a>) and this is the same advice I would give you, which is to measure your code and see what performance differences you are getting between a baseline test and your test running single threaded: <ol> <li>Time required to insert data using single thread to map with above listed data </li> <li>Time required to insert data using single thread to map with above listed data and using mutex locks</li> </ol> If you are still looking for a thread-safe container, you may want to look at Intel's open-source implementation of thread-safe containers at <a href="http://www.threadingbuildingblocks.org/docs/help/reference/containers_overview/concurrent_queue_cls.htm" rel="nofollow">http://www.threadingbuildingblocks.org/docs/help/reference/containers_overview/concurrent_queue_cls.htm</a> . Also, as a suggestion for the consumer thread implementation, you may want to read the ActiveObject article that Herb Sutter posted on his website: <a href="http://herbsutter.com/2010/07/12/effective-concurrency-prefer-using-active-objects-instead-of-naked-threads/" rel="nofollow">http://herbsutter.com/2010/07/12/effective-concurrency-prefer-using-active-objects-instead-of-naked-threads/</a> If you can provide some more details, like why the map has to be locked all the time, we may be able to draft up a mechanism that is better performing.

Guidance

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.
