Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Stop Guessing, Start Measuring: Transform Your Code with BenchmarkDotnet!
Let’s look at the first example you see, when you open up BenchmarkDotnet’s website, or Github page.
-
Benchmarking 20 programming languages on N-queens and matrix multiplication
Or use BenchmarkDotNet which, among other things to get an accurate benchmark, does JIT warmup outside of measurement.
( https://github.com/dotnet/BenchmarkDotNet ).
-
How to improve C# performance on matrix multiplication example?
You can also do proper statistically correct benchmarking by using - https://github.com/dotnet/BenchmarkDotNet. This will run warmup the jit, gauge the overheads, and run your function many times to give you proper data.

C# Memory Profiler on VSCode

standard events vs MVVM Reference Messenger
Yes, weak references are slower than direct calls. How much slower? Heck if I know offhand. But it's usually pretty easy to set up something with Benchmark .NET and find out if it hurts your use case.
-
Mechanisms and Performance when querying data to SQLServer from C#
For this purpose we are going to use our beloved BenchmarkDotNet tool.
-
Object Mapping in .NET
To quantify and compare the performance of the object mapping strategies discussed earlier, we can employ BenchmarkDotNet.

Exploring Code Performance Testing in C# with BenchmarkDotNet
BenchmarkDotNet is a popular open-source library that, as stated in the repo's README.md, helps us to transform methods into benchmarks, track their performance, and share reproducible measurement experiments. Using BenchmarkDotNet feels similar to writing unit tests. It's very important to note that the library only works with console apps. Finally, we can visualize the results in the terminal where the benchmark ran or in user-friendly formats such as markdown, HTML and CSV. We will explore examples of there formats later in the article.

Is it okay to lock on a StringBuilder, on which StringBuilrer I perform some operations on?
However, obviously this prevents parallelism within the lock, so this only makes sense if you do some other expensive operation in the parallel loop and the string builder is only a small part of it. Performance wise, it may be better to concatenate the results together after the parallel operation, instead of locking inside the loop. You'll have to benchmark it to know for sure.
-
Iterator Benchmarks That Shocked With Unexpected Results!
We’re of course going to be using BenchmarkDotNet for our benchmarks, and you can find all of the code for these over at GitHub. To start, we need an entry point hook for our single Benchmark class that will be defining the permutations of scenarios that we’d like to run. This will be relatively basic as follows:

I wrote useful Microsoft ILogger<TCategoryName> analyzer, which helps you to find mistakes in your code
The other comment here is probably a good start. There may be some guidance over at https://github.com/dotnet/roslyn-analyzers on how to write high-performance analyzers. But your code is simple enough that I'm not sure it's a huge concern.

Moreover, in the Roslyn Analyzers issue tracker, was created the task of developing a new diagnostic that would detect such cases.

Library authors, be really careful with Type.GetMethod(string). It is a backwards compatibility nightmare.
Like the other person said, one way is to look at code analyzers, e.g. https://github.com/dotnet/roslyn-analyzers/blob/a0522afd52b25ad211298e308fd5bbc7734865e0/src/PerformanceSensitiveAnalyzers/CSharp/CodeFixes/AvoidAllocationWithArrayEmptyCodeFix.cs
What are some alternatives?
App.Metrics - App Metrics is an open-source and cross-platform .NET library used to record and report metrics within an application.
StyleCop - Analyzes C# source code to enforce a set of style and consistency rules.
CodeMaid - CodeMaid is an open source Visual Studio extension to cleanup and simplify our C#, C++, F#, VB, PHP, PowerShell, JSON, XAML, XML, ASP, HTML, CSS, LESS, SCSS, JavaScript and TypeScript coding.
Metrics-Net - The Metrics.NET library provides a way of instrumenting applications with custom metrics (timers, histograms, counters etc) that can be reported in various ways and can provide insights on what is happening inside a running application.
Gendarme - Gendarme is a extensible rule-based tool to find problems in .NET applications and libraries. Gendarme inspects programs and libraries that contain code in ECMA CIL format (Mono and .NET) and looks for common problems with the code, problems that compiler do not typically check or have not historically checked.
NsDepCop - NsDepCop is a static code analysis tool that helps to enforce namespace dependency rules in C# projects. No more unplanned or unnoticed dependencies in your system.
Bogus - :card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
AspNet.Metrics - No longer maintained, instead see - https://github.com/alhardy/AppMetrics/
