Unleashing .NET 9: Key Performance Boosts and Pitfalls Compared to .NET 8
Overall, based on all the tests I conducted; .NET 9 is approximately 1.11 times faster than .NET 8—a notable improvement for an interim release!
.NET 9 LINQ Performance Improvements
Benchmark comparisons between .NET 8 and .NET 9 show that certain LINQ queries execute up to 30% faster, depending on the dataset and query complexity. These improvements are particularly impactful for performance-critical applications, where even small gains can add up to substantial boosts.
.NET 9.0 LINQ Performance Improvements
With .NET 9, LINQ becomes faster in several common scenarios. As with every new version of .NET, you simply need to migrate and recompile to take advantage of these improvements. Additionally, LINQ has been optimized in other ways: SIMD is utilized whenever possible, such as when summing a sequence of integers. Moreover, enumerating empty sequences incurs lower costs due to early detection.

در نگارش‌های اخیر دات‌نت، NET CLI. به همراه تغییرات قابل توجهی بوده‌است که در این مطلب و نظرات آن، موارد مهم این تغییرات را بررسی خواهیم کرد.
console logger بهبود یافته‌ی دات‌نت 8
یکی از تغییرات بسیار جالب توجه و مفید NET CLI. در دات‌نت 8، امکان دسترسی به خروجی لاگ‌های ساختار یافته‌ی اعمال خط فرمان آن است:
اگر پروژه‌ی خود را با استفاده از دستور dotnet build، کامپایل می‌کنید، خروجی پیش‌فرض این دستور خط فرمان، کلی و بدون ارائه‌ی جزئیات است؛ اما می‌توان آن‌را در دات‌نت 8، به شکل تصویر فوق، تغییر داد و به این مزایا رسید:
- امکان مشاهده‌ی زمان کامپایل هر قسمت به صورت جداگانه
- امکان مشاهده‌ی پویای درصد انجام عملیات
- امکان مشاهده‌ی جزئیات کامپایل هر target framework به صورت مجزا
- دسترسی به یک خروجی رنگی و زیباتر
این خروجی را که به صورت پیش‌فرض فعال نیست، می‌توان به دو صورت:
الف) سراسری و با اجرای دستور PowerShell زیر:
[Environment]::SetEnvironmentVariable("MSBUILDTERMINALLOGGER", "auto", "User")که متغیر محیطی MSBUILDTERMINALLOGGER را به auto تنظیم می‌کند،
ب) و یا با استفاده از سوئیچ tl-- به ازای هر دستور dotnet build، به صورت جداگانه‌ای فعال کرد:
dotnet build --tl
یک نکته: این قابلیت جالب و مهم، در دات نت 9، به صورت پیش‌فرض فعال است و نیازی به تنظیم خاصی ندارد.
