Memory Usage Under Lion?

Postby Jonathan.F » Fri Dec 02, 2011 9:36 am

I'm seeing what I believe to be unusual patterns of memory usage by my 4.7.3 standalone application under Lion.

When I first launch the application the memory profile looks like this:

memory_usage_immediately_after_startup.gif
memory_usage_immediately_after_startup.gif (8.82 KiB) Viewed 2411 times


If I put the application into the background (idling without any significant background operations) these numbers quickly creep up. After 24 hours I am seeing a private memory size of 34.8 MB and a real memory size of 57.1 MB.

memory_usage_after_approximately_24_hours_open_but_idle.gif
memory_usage_after_approximately_24_hours_open_but_idle.gif (8.9 KiB) Viewed 2411 times


And the statistics are:

statistics_after_approximately_24_hours_open_but_idle.gif
statistics_after_approximately_24_hours_open_but_idle.gif (17.32 KiB) Viewed 2411 times


Is this 'normal' behavior for Lion? Does it suggest a memory leak? Is there something I'm doing that might be causing this? Any suggestions welcomed!

Thanks!

It doesn't sound normal… does the memory footprint continue to grow?

In leaving some of my standalones open for the better part of a day, I am not seeing any increase in memory usage.

Yes the memory usage appears to continue to grow.
