<P>With the help from this forum we have been making progress understanding our memory usage. See the separate thread: [Laszlo-user] Understanding memory analysis when using _LzDebug.whyAlive()</P>
<P>We're now at the point were we see that the "smoots" taken up by Laszlo objects are not all of our memory usage. It seems a large part (large percentage of total RAM usage, maybe even more than 50%) may be used elsewhere, perhaps in the Flash objects that are "underneath" the Laszlo objects.</P>
<P>Questions:</P>
<OL>
<LI>Is there any tool or technique that allows us to analyze exactly how this memory is being used by Flash? ("underneath" the laszlo objects, I mean)</LI>
<LI>Are there any guidelines to help us optimize this Flash part of our memory usage?</LI>
<LI>More generally is there any way to use Flash-specific optimization techniques (going to the ActionScript where necessary). We know that in pure Flash there are several optimization techniques; the following points are examples of things we wish to try</LI>
<LI>Can we in general call pieces of ActionScript from Laszlo script?</LI>
<LI>Bitmap caching:</LI>
<UL>
<LI>SWF resources can be translated once into bitmaps (on the client side) and cached</LI>
<LI>you probably know this is known as bitmap caching.</LI>
<LI>Then the bitmaps are used repeatedly instead of rendering the SWF objects repeatedly. </LI>
<LI>Can we do Bitmap Caching for all those vector graphics which do not change frequently (from Laszlo, but possibly with specific usage of Actionscript if necessary)</LI></UL>
<LI>Garbage collection: we would like to trigger the Flash garbage collection just to test what is going on (as a test not permanent change). Any way for us to do this?</LI></OL>
<P>Thank you</P>
