Benchmarks indicate big performance improvements in .NET 6 – gHacks Tech News

[ad_1]

The upcoming next major version of Microsoft .NET, .NET 6, improves performance of many operations significantly according to Microsoft’s benchmark tests.

A new post on the Dotnet developer blog by Stephen Toub,
Partner Software Engineer, .NET, offers insights on the benchmark tests and the performance improvements compared to previous versions of .NET.

According to the post, about 6500 merged pull requests landed in .NET 6, excluding automated pull requests by bots. Of these, about 550 improve performance in one area or another, according to Microsoft.

The post is technical in nature; it contains a lot of code, examples and instructions to run the benchmark to verify the results. BenchmarkDotNet was used for the majority of results.

As examples, here are the benchmark results of Just In Time benchmark tests. Most tests compare the performance of .NET 6.0 with .NET 5.0, but you find other .NET versions used in some of the tests as well.
