Why does my Linux application use so much memory?

Heaptrack is a fast heap memory profiler that runs on Linux. It allows you to track all heap memory allocations at run-time. Afterwards, the accompanying GUI tool can be used to find optimization opportunities in your code by analyzing the recorded profiling data.

Heaptrack traces all memory allocations and annotates these events with stack traces. Dedicated analysis tools then allow you to interpret the heap memory profile to:
- find hotspots that need to be optimized to reduce the memory footprint of your application
- find memory leaks, i.e. locations that allocate memory which is never deallocated
- find allocation hotspots, i.e. code locations that trigger a lot of memory allocation calls
- find temporary allocations, which are allocations that are directly followed by their deallocation
- measure differences in all of the above before and after changing the code

You can use heaptrack pretty much wherever you are using Linux – it has been successfully used on 32bit and 64bit flavors of x86 and ARM platforms, both on embedded projects as well as desktop applications.
