General Performance Tip: Enhanced Logging Approach
The article discusses advancements in logging techniques in .NET, particularly with the new source generator in .NET 6 that enhances performance using LoggerMessage. This new method improves logging efficiency by 11.25 times compared to previous approaches. It emphasizes the importance of extensive logging for issue resolution in code.
Optimizing String Concatenation in C# with Spargine FastStringBuilder
Explore enhanced string concatenation in C# programming with the FastStringBuilder from DotNetTips.Spargine.Core, utilizing the ConcatStrings() method for optimized performance. Benchmark results reveal a 1.107 times performance improvement and reduced memory allocations, making it a valuable tool for efficient string manipulation.
Collection Performance: Comparing Byte Array’s with SequenceEqual()
LINQ's SequenceEqual() method compares two Byte arrays, returning a Boolean indicating equal length and matching elements. Access more on collection performance by subscribing.
General Performance Tip: Handling Exceptions
In my presentation at the Silicon Valley Code Camp, a question about the performance of using the When() clause for catching exceptions prompted me to conduct performance testing. While traditional exception handling is crucial, my testing revealed that the When() clause is more performant when capturing multiple similar exceptions.
Collection Performance: Comparing ImmutableArray<>’s with SequenceEqual()
The ImmutableArrayExtensions contain a SequenceEqual() method for comparing ImmutableArray items. The method compares elements using the default equality comparer for TSource and can be used with a for() loop for performance validation.
General Performance Tip: Comparing ComputeHash(), HashData(), and TryHashData() Methods
Developers can simplify hashing byte arrays by using HashData() instead of ComputeHash(), as it requires less code and eliminates the need to manage the SHA256 object. Benchmarking shows HashData() is about 1.16x faster than ComputeHash() and 1.02x faster than TryHashData(). EditorConfig helps manage related diagnostics.
General Performance Tip: Creating an Object
In this investigation of object creation in .NET, various methods were explored, including "new" keyword, Activator.CreateInstance, and RuntimeHelpers.GetUninitializedObject.
General Performance Tip: Avoid Unnecessary Variable Initialization
In the analysis of code, it's noted that explicit initialization of variables, when the default state is already set, can impact performance. Situations requiring variable initialization are discussed, with examples showing unnecessary explicit initialization. The default values for reference types and the default values for properties of a custom type are also examined.
String Performance: Comparing Strings with Globalization
In the String Performance chapter of the code performance book, the author demonstrates the usage of string.Compare() with StringComparison. Benchmark results are provided, along with a recommendation to use cultures or ordinals based on the strings being compared. The chapter also touches on setting up EditorConfig for dotnet_diagnostic.CA1862.
