Turbocharged: Writing High-performance C# and .NET code

on YouTube ↗01h 14m

" summary

Shows concrete wins: microbenchmarks with Benchmark.NET drop a key-builder from ~1000 ns to ~400 ns and cut allocations ~6x, saving roughly 17 GB/day on an 18M‑message service; CSV ingest drops from 8.5 s to <1 s and allocations from 7.2 GB to 242 MB (30x), using pipelines and span parsing; JSON happy path short‑circuits to ~485 ns with near‑zero allocations using low‑level UTF‑8 reader. Uses Span<T> with stackalloc under 256 chars, rents via ArrayPool, and opts into System.Text.Json for low‑allocation parsing.
