Is this in all browsers? I know IE 6 (maybe even 7?) has issues with
memory management. I consistently see memory leak-like behavior with IE
6, for example: 

 

Start debug session for basic app - IE reports 60+ MB memory usage with
a value that steadily climbs as I use the app.

Minimize the browser, then bring it back to view - IE memory usage drops
to ~13 MB.

Use the app for a few more minutes, memory footprint grows in size a few
MB.

Minimize, then restore - IE footprint back down to ~13 MB or so.

 

I don't see the same behavior in FF, which is good. The issue might be
with memory management within that particular browser, and not the Flash
Player. 

 

HTH,

Ryan

Subject: [flexcoders] Memory consumption by the browser

 

Hi everybody,

I am trying to solve the problem when my application consumes a lot of
memory.
When application starts in the browser, Windows/Mac reports the size
of browser process around 150Mb.
Then, if you start opening/closing the same popup window (which is
actually being cached by application), the browser starts to grow. 
Each appearance of popup consumes around 1.5Mb [sic!] (the consumer is
childConstraintInfo, around 256 instances)
When you close the pop up, memory sometimes goes down, but never to
the original value. Never ever. At least 100-200kb more at a time.

OK, when I use a profiler, it shows that application consumes 42Mb. 
Profiler shows no leaks, even if the number of instances are growing,
when I click on GarbageCollector icon it always goes to the original
figures, including childConstraintInfo instances. Total Memory stays
at 42Mb mark. Good.
But the problem is that browser's footprint is still growing. After a
couple of hours of work with application it grows to 500-600Mb.

In profiler everything looks perfect. In reality - 600Mb app on 1Gb
system makes it dead.

The question is, what makes browser to be so memory hungry? Why it
consumes more & more memory without any attempt to release it? 

The simplest action with panel instance addPopUp/removePopUp consumes
1.5Mb of memory - I don't believe it. Well, the panels has 3 states
and complex layout with ~100 elements. But what makes it so different
to the "Hello, World" popup, which seems to be right?

Thank you for any thought in advance.

Regards,
Dmitri.
