Excessive garbage allocation

How to find excessive garbage allocation?

Purpose: Reduce time that garbage collector spends on collecting temporary objects.

If garbage collection takes a significant amount of time, it is advised to profile memory allocation to pin-point and optimize the problematic code.

Let us assume there is a task in your application that you want to profile.

  • Start object allocation recording with default settings right before the task is started.
  • Wait until the task finishes or performs long enough.
  • Capture memory snapshot and stop object allocation recording.
  • Open snapshot and use Garbage Collection view.

Optionally, the profiled application can be launched with object allocation recording started with the help of corresponding startup options.
