Why Your .NET App Is Slow!
Tools like DotTrace, PerfView, and others can help you identify and resolve them
Performance issues in production can be the bane of any .NET developer’s existence. Despite your best efforts during development, a slow .NET application in production might frustrate users, hurt business metrics (when you hurt their money! You hurt their sentiments), and damage your reputation.
The good news? Tools like dotTrace, PerfView, and others can help you identify and resolve these issues.
This article is all about how to use profiling tools effectively, look through issues, and provide actionable solutions to improve performance. Along the way → we’ll discuss best practices, common mistakes, and real-life scenarios — complete with examples and performance benchmarks.
What Causes Performance Issues in .NET Applications?
Performance problems often stem from complex interactions between your application’s code, the runtime, and the environment.
Common causes include:
- High CPU usage: Inefficient algorithms or unnecessary processing.
- Memory leaks: Objects that aren’t properly disposed of, causing the memory footprint to grow over time. [ think of it ]
- Excessive I/O operations: Slow database queries, frequent file access, or messy network communication.
- Thread contention: Multiple threads competing for shared resources.
- Blocking operations: Synchronous code in a predominantly asynchronous application!
📌To diagnose these issues in a production environment, you need profiling tools that can provide deep insights without significantly impacting performance…
Profiling Tools
Profiling tools collect detailed data about your application’s behavior during execution. This data helps identify:
- Hot paths in the code.
- spent in specific methods.
- Memory allocation patterns.
- Thread activity and contention points.
Two of the most powerful profiling…
