Hi Torsten,

The panel indeed consumes memory and it is a good idea to mention it in the documentation. We should do the same with threads, because I have notices that every time you place the mouse over the panel, the system creates two threads.

By the way, a useful tip for using the panel is to go to Options->Update and then unclick the option "Require Mouse over Panel". Setting the Update Time to 500ms is also something I usually do.

cheers

Dear all,

I am just studying the memory consumption of some program with the handy system panel.

I noticed that whenever the panel is constantly updating (i.e. when the mouse pointer is over the Panel's window), the current heap size increases by about 3 K per second -- even if no other Oz code at all is loaded. As soon as the mouse is removed from the panel, the size stays where it is. So, this memory consumption is probably caused by the panel itself.

I was far a while searching what my program does wrong before I figured this out. It is of course totally fine that the panel reports its own memory consumption, but some hint in the documentation might be helpful.

Can anyone confirm that this is indeed the case? Would it be OK then, if I add a brief remark to the Panel doc (e.g., at http://www.mozart-oz.org/documentation/panel/node3.html#chapter.usage.memory)?

Thanks!

Best
Torsten
