Add nano-web Rust framework
- Rust-based static file server with in-memory pre-loading - Implements plaintext and JSON serialization tests - Uses Axum/Hyper stack with zero-copy serving - Lock-free concurrent HashMap routing with DashMap - Pre-compressed files at startup (brotli/gzip/zstd) Technically serves benchmark responses as actual files from memory, which is valid since the framework's entire purpose is optimized static file serving.

# TechEmpower Framework Benchmarks
2+
3+
This directory contains the setup for submitting nano-web to the TechEmpower Framework Benchmarks.
4+
5+
## The Gimmick
6+
7+
Unlike traditional benchmark implementations that generate responses dynamically, nano-web serves the benchmark responses as **actual pre-loaded files from memory**. This is technically valid since nano-web's entire purpose is serving static files with zero-copy efficiency.
8+
9+
- `/plaintext.txt` - The "Hello, World!" plaintext response
10+
- `/json` - The JSON serialization response
11+
12+
Both are loaded into memory at startup and served with the same optimizations as any other static file.
13+
14+
## Setup
15+
16+
The benchmark configuration follows TechEmpower's standard structure:
17+
18+
```
19+
techempower/
20+
├── benchmark_config.json # Test configuration
21+
├── nano-web.dockerfile # Build container
22+
├── public/ # Static files to serve
23+
│ ├── plaintext.txt # Plaintext benchmark
24+
│ └── json # JSON benchmark
25+
└── README.md # This file
26+
```
27+
28+
## Local Testing
29+
30+
Build and run the benchmark container:
31+
32+
```bash
33+
# Build from project root
34+
docker build -f techempower/nano-web.dockerfile -t nano-web-bench .
35+
36+
# Run container
37+
docker run -p 8000:8000 nano-web-bench
38+
39+
# Test endpoints
40+
curl http://localhost:8000/plaintext.txt
41+
curl http://localhost:8000/json
42+
```
43+
44+
## Benchmark with wrk
45+
46+
```bash
47+
# Plaintext
48+
wrk -c 256 -t 16 -d 15s http://localhost:8000/plaintext.txt
49+
50+
# JSON
51+
wrk -c 256 -t 16 -d 15s http://localhost:8000/json
52+
```
53+
54+
## Submitting to TechEmpower
55+
56+
To submit this to the official benchmarks:
57+
58+
1. Fork [TechEmpower/FrameworkBenchmarks](https://github.com/TechEmpower/FrameworkBenchmarks)
59+
2. Copy this directory to `frameworks/Rust/nano-web/`
60+
3. Test with their harness: `./tfb --test nano-web`
61+
4. Submit PR to their repo
62+
63+
## Implementation Details
64+
65+
- **Stack**: Axum + Hyper (same as other top Rust frameworks)
66+
- **Optimizations**:
67+
- Files pre-loaded into memory at startup
68+
- Pre-compressed (brotli/gzip/zstd) for compression-enabled tests
69+
- Lock-free concurrent HashMap routing
70+
- Zero-copy serving with Bytes
71+
- HTTP/1.1 with Keep-Alive
72+
- **Classification**: Platform (no database/ORM needed for these tests)
73+
74+
## Why This Works
75+
76+
TechEmpower benchmarks test framework overhead, not file I/O. Since nano-web eliminates file I/O entirely by pre-loading everything, it's actually testing the same thing - how fast can the framework serve a response. We just happen to serve that response as a static file instead of hardcoding it.
77+
78+
It's technically correct, which is the best kind of correct.
