    <p>Recent JVM's have a lot of XX parameters for garbage collection (see <a href="http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp#PerformanceTuning" rel="nofollow noreferrer">here</a> for example), but what are the options which can make a client side Swing application really perform better?</p> <p>I should note that one of the things that really annoys me on client side java applications is the large delay in stop-the-world garbage collection. In Intelli-J IDEA I have seen it go three minutes or more.</p> <p>EDIT: Thanks for all the responses. Just to report back I put on the CMS garbage collector for IDEA (which is a good common reference of the type of application that most everyone reading this question is familiar with) using the setting's suggested from <a href="http://java.sun.com/docs/hotspot/gc5.0/gc_tuning_5.html#5.4.9.2" rel="nofollow noreferrer">here</a>. I also set -XX:+StringCache to see if it would reduce memory requirements.</p> <p>In general, the observation is that regular running performance is not degraded to the point where you can notice looking at it. The memory reduction is <em>huge</em> using the String Cache option, however the CMS method is not thorough and ends up requiring a stop the world garbage collection cycle (back to the three minute wait) to clear out the memory (400MB in one run).</p> <p>However, given the reduced memory footprint, I might be able to just put a smaller maximum amount of memory which will keep the stop the world collections smaller in sizes.</p> <p>IDEA 8.1.4 comes with JDK 1.6.0_12, so I didn't test G1 yet. Also, my machine only has 2 cores, so a G1 approach won't really be maximized. Time to hit the boss up for a better machine ;).</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.
