Here you can define at what interval KNewsTicker queries the configured news sources for new headlines. This depends generally on how fast you would like to hear about news and how much load you want to put on the network:<ul>
<li>A lower value (lower than <b>15 minutes</b>) enables you to get notified about news very quickly if you want or need to. Please note that it increases the network traffic significantly, though. Therefore, such low values should not be used if you query popular news sites (such as <a href="http://slashdot.org">Slashdot</a> or <a href="http://freshmeat.net">Freshmeat</a>) as they have generally already enough work processing the incoming queries.</li>
<li>A higher value (higher than <b>45 minutes</b>) will make you hear about news less quickly. For non-timecritical applications, it should be suitable, though. The positive aspect of longer intervals is that only very little load is put on the network; this saves resources and nerves, for you and the system administrators of the news sites you query.</li></ul>
The default value (30 minutes) should be appropriate and reasonable in most cases.
