Excessive garbage allocation

How to find excessive garbage allocation?

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

• Run application with the profiler
• Connect to application.
• Garbage collection telemetry will help you estimate garbage collector load.

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.
