Adding Startup Time Analysis Capability

[mackoj]

Hello @marinofelipe,

I'm reaching out to propose an enhancement that I believe could open the door to a plethora of new valuable metrics.

I aim to enable users to extract the startup time in order to compare with or without the SDK. The proposed functionality would involve executing the application both with and without the SDK multiple times, capturing the startup times for each iteration. Subsequently, the average startup time for each scenario would be calculated, allowing users to compare the performance impact of integrating the SDK.

The output could be presented as either the percentage increase in startup time or the absolute time difference. I am open to discussing the most appropriate format based on the project's requirements and user preferences.

Additionally, implementing this feature would pave the way for extracting more data from MetricKit in the future.

But implementing this will require MeasurementApp to run on device.

I would appreciate your thoughts and feedback.

The proof of concept have generated this.

{
  "applicationLaunchMetrics" : {
    "average" : 1867.1428571428571
  }
}

Thank you
