Line-by-Line Profiling JetBrains dotTrace 2024.1: Getting Started

Getting Started with JetBrains dotTrace 2024.1: Line-by-Line Profiling

JetBrains dotTrace is a powerful performance profiling tool for .NET applications. In this article, we will focus on how to use dotTrace 2024.1 for line-by-line profiling, covering the following profiling modes: Sampling, Timeline, and Tracing.

Prerequisites

Before we begin, make sure you have the following:

• A .NET application to profile
• JetBrains dotTrace 2024.1 installed

Profiling Modes

dotTrace offers several profiling modes, each with its own advantages and use cases. In this article, we will focus on the following modes:

• Sampling: This mode periodically takes snapshots of the application's execution and is useful for quick performance assessments.
• Timeline: This mode captures detailed information about all application threads, including their states, call stacks, and allocated objects.
• Tracing Line-by-Line: This mode provides a detailed breakdown of method execution times, including the time spent in each line of code.

Profiling with Sampling Mode

To start profiling with Sampling mode, follow these steps:

1. Launch dotTrace and select Start Performance Profiling.
2. Choose Sampling as the profiling type and select your application's executable.
3. Configure the profiling settings as desired and click Run.
4. After the profiling session ends, dotTrace will display the results, highlighting the most time-consuming methods.

Profiling with Timeline Mode

To start profiling with Timeline mode, follow these steps:

1. Launch dotTrace and select Start Performance Profiling.
2. Choose Timeline as the profiling type and select your application's executable.
3. Configure the profiling settings as desired and click Run.
4. After the profiling session ends, dotTrace will display the results, including detailed information about all application threads and their call stacks.

Profiling with Tracing Line-by-Line Mode

To start profiling with Tracing Line-by-Line mode, follow these steps:

1. Launch dotTrace and select Start Performance Profiling.
2. Choose Tracing Line-by-Line as the profiling type and select your application's executable.
3. Configure the profiling settings as desired and click Run.
4. After the profiling session ends, dotTrace will display the results, providing a detailed breakdown of method execution times, including the time spent in each line of code.

JetBrains dotTrace 2024.1 is a powerful performance profiling tool for .NET applications. By understanding how to use its Sampling, Timeline, and Tracing Line-by-Line profiling modes, you can quickly identify performance bottlenecks and optimize your application's code.
