<p>You can try different values of <code>NO_OF_OBJECTS</code>
constant to see the difference. </p>
<p>If the value of <code>NO_OF_OBJECTS</code> is high
(>1,000,000) you may notice that the memory consumption increases a lot. In
order to decrease it, try using:</p>
<span name="cs_wiki_filter" csw_filters="cs"><p>c#: </p>
<p><code>container.Ext().Configure().ClientServer().MaxBatchQueueSize(size);</code></p>
</span>
<span name="cs_wiki_filter" csw_filters="vb"><p>VB: </p>
<p><code>container.Ext().Configure().ClientServer().MaxBatchQueueSize(size);</code></p>
</span>
<p>Specify the size parameter according to the desirable memory
consumption limit.</p></div>
