Parallelism on a Single Core — SIMD with C#

Your .NET API is Processing 10,000 Records in 2 Seconds Here’s How to Make it 200ms

Let’s kick things off with what SIMD actually means.

🕸️What Is SIMD and How We Implement It in .NET?

— Instead of tackling tasks one-by-one like an assembly line, SIMD lets your machine juggle multiple pieces of data with a single instruction. This multitasking happens thanks to specialized hardware that splits data into batches, processing them simultaneously…

So, how do we harness this power in .NET?

You tried async/await. Added caching. Optimized your database queries. Your API still chokes when processing large datasets! isn’t it?

🕸️Nobody Talks About —

Your API endpoint receives 10,000 order records. Each needs a calculation — tax, discount, total. Simple math.
