🚀 Performance: At the Edge of Physics

Tachyon 0.7.2 is not just a library; it is a weapon of mass optimization. Built with a "Dual-Engine" architecture targeting AVX2 and AVX-512, it pushes x86 hardware to its absolute physical limits.

🏆 Benchmark Results: AVX-512 ("God Mode")

Environment: [ISA: AVX-512 | ITERS: 50 | WARMUP: 20]

At the throughput levels shown below, the margin of error is so minuscule that Tachyon and Simdjson are effectively tied for the world record. Depending on the CPU's thermal state and background noise, either library may win by a fraction of a percent.

Dataset	Library	Speed (MB/s)	Median Time (s)	Status
Canada.json	Tachyon (Turbo)	10,538.41	0.000203	👑 JOINT WORLD RECORD
Canada.json	Simdjson (Fair)	10,247.31	0.000209	Extreme Parity
Canada.json	Glaze (Reuse)	617.48	0.003476	Obsolete

🏛️ The Four Pillars of Quasar

1. Mode::Turbo (The Throughput King)

Optimized for Big Data analysis where every nanosecond counts.

• Technology: Vectorized Depth Skipping. Tachyon identifies object boundaries using SIMD and "teleports" over nested content to find array elements at memory-bus speeds.

2. Mode::Apex (The Typed Speedster)

The fastest way to fill C++ structures from JSON.

• Technology: Direct-Key-Jump. Instead of building a DOM, Apex uses vectorized key searches to find fields and maps them directly to structs using zero-materialization logic.

3. Mode::Standard (The Balanced Warrior)

Classic DOM-based access with maximum flexibility.

• Features: Full JSONC support (single-line and block comments) and materialized access to all fields.

4. Mode::Titan (The Tank)

Enterprise-grade safety for untrusted data.

• Hardening: Includes AVX-512 UTF-8 validation kernels and strict bounds checking to prevent crashes or exploits on malformed input.

🛠️ Usage Guide

Turbo Mode: Fast Analysis

Best for counting elements or calculating statistics on huge buffers.

#include "Tachyon.hpp"

Tachyon::Context ctx;
auto doc = ctx.parse_view(buffer, size); // Zero-copy view

if (doc.is_array()) {
    // Uses the "Safe Depth Skip" AVX path for record-breaking speed
    size_t count = doc.size(); 
}

Apex Mode: Direct Struct Mapping

Skip the DOM entirely and extract data into your own types.

struct User {
    int64_t id;
    std::string name;
};

// Non-intrusive metadata
TACHYON_DEFINE_TYPE_NON_INTRUSIVE(User, id, name)

int main() {
    Tachyon::json j = Tachyon::json::parse(json_string);
    User u;
    j.get_to(u); // Apex Direct-Key-Jump fills the struct instantly
}

🧠 Architecture: The Dual-Engine

Tachyon detects your hardware at runtime and hot-swaps the parsing kernel.

• AVX2 Engine: 32-byte-per-cycle classification using vpshufb tables.
• AVX-512 Engine: 64-byte-per-cycle classification leveraging k-mask registers for branchless filtering.
