‫مقایسه سرعت دات‌نت 9 با Go و Node.js

ASP.NET Core 8 is 10x faster than Node.js. In .NET 9, it's faster. Here's why:

𝗝𝗜𝗧: The Just-In-Time (JIT) compiler in .NET 9 enhances code generation for faster performance.

𝗣𝗚𝗢: Dynamic Profile Guided Optimization (PGO) optimizes casts and tracks common input types for better efficiency.

𝗧𝗶𝗲𝗿 𝟬: Tier 0 optimizations reduce startup overhead by avoiding unnecessary boxing and improving async/await.

𝗟𝗼𝗼𝗽𝘀: Loop optimizations include strength reduction and downward counting for more efficient execution.

𝗕𝗼𝘂𝗻𝗱𝘀 𝗖𝗵𝗲𝗰𝗸𝘀: Enhanced bounds check elimination ensures memory safety with minimal performance impact.

𝗔𝗿𝗺𝟲𝟰: Significant Arm64 improvements include better code generation and optimizations for common patterns.

𝗔𝗥𝗠 𝗦𝗩𝗘: Scalable Vector Extension (SVE) support improves vectorized operations on ARM architectures.

𝗔𝗩𝗫𝟭𝟬.𝟭: AVX10.1 instructions boost performance for computationally intensive tasks on compatible hardware.

𝗔𝗩𝗫𝟱𝟭𝟮: AVX512 support enhances performance for data-parallel operations and numerical computations.

𝗩𝗲𝗰𝘁𝗼𝗿𝗶𝘇𝗮𝘁𝗶𝗼𝗻: Better vectorization leads to efficient execution of parallelizable operations.

𝗕𝗿𝗮𝗻𝗰𝗵𝗶𝗻𝗴: Improved branch prediction reduces penalties from mispredicted branches.

𝗪𝗿𝗶𝘁𝗲 𝗕𝗮𝗿𝗿𝗶𝗲𝗿𝘀: Optimized write barriers minimize garbage collection overhead for better memory management.

𝗢𝗯𝗷𝗲𝗰𝘁 𝗦𝘁𝗮𝗰𝗸 𝗔𝗹𝗹𝗼𝗰𝗮𝘁𝗶𝗼𝗻: Reduces heap allocations for short-lived objects, improving performance.

𝗜𝗻𝗹𝗶𝗻𝗶𝗻𝗴: Enhanced inlining reduces function call overhead for more efficient execution.

𝗚𝗖: Garbage Collection improvements lower pause times and enhance responsiveness.

𝗩𝗠: Virtual Machine enhancements improve resource utilization and managed application performance.

𝗠𝗼𝗻𝗼: Mono runtime improvements lead to faster execution on platforms that use Mono.

𝗡𝗮𝘁𝗶𝘃𝗲 𝗔𝗢𝗧: Native Ahead-of-Time (AOT) compilation offers significant performance gains by pre-compiling to native binaries.

𝗧𝗵𝗿𝗲𝗮𝗱𝗶𝗻𝗴: Threading optimizations improve multi-threaded application efficiency and throughput.

𝗥𝗲𝗳𝗹𝗲𝗰𝘁𝗶𝗼𝗻: Improved reflection reduces the overhead of dynamic type inspection and invocation.

𝗡𝘂𝗺𝗲𝗿𝗶𝗰𝘀: Numerical computation enhancements make mathematical operations faster and more accurate.

𝗣𝗿𝗶𝗺𝗶𝘁𝗶𝘃𝗲 𝗧𝘆𝗽𝗲𝘀: Optimizations for primitive types improve performance for basic data operations.

And several other improvements across 350+ performance-related PRs went into .NET 9.
