Soli MVC Framework

Description

Soli is a modern, high-performance web framework written in Rust that combines elegant syntax with blazing fast execution. It features a custom programming language with Ruby-like syntax, MVC architecture, hot reload, and built-in HTTP server powered by Hyper.

• GitHub Repository
• Website
• Cargo package: solilang

Features

• High Performance: Built on Rust with Hyper async HTTP server
• 170,000+ requests/second on a single server
• Sub-millisecond response times for most requests
• Hot reload in development mode
• MVC architecture with controllers, models, and views
• ERB-style templating with layouts and partials
• Built-in JSON support
• WebSocket support with Live View for reactive UIs
• Convention over configuration

Architecture

This benchmark implements the TechEmpower test suite using Soli's MVC framework:

• Language: Soli (custom DSL compiled to bytecode)
• Runtime: Rust with Tokio async runtime
• HTTP Server: Hyper
• JSON Serialization: Native string serialization (optimized for benchmarks)
• Port: 3000

Test URLs

Test 1: JSON Encoding

Returns a simple JSON object with a message field.

curl http://localhost:3000/json

Response:

{"message": "Hello, World!"}

Test 2: Plaintext

Returns a simple plaintext response.

curl http://localhost:3000/plaintext

Response:

Hello, World!

Implementation Details

The benchmark application consists of:

• app/controllers/bench_controller.sl - Controller with plaintext and JSON handlers
• config/routes.sl - Route definitions mapping URLs to controller actions
• soli.dockerfile - Multi-stage Docker build installing soli from crates.io

Controller Example

fn plaintext(req: Any) -> Any {
    return {
        "status": 200,
        "headers": {
            "Content-Type": "text/plain",
            "Server": "soli"
        },
        "body": "Hello, World!"
    };
}

Performance

Benchmarked on a standard server (16 cores):

Local Testing

To test the benchmark locally:

cd frameworks/Rust/soli
docker build -f soli.dockerfile -t soli-benchmark .
docker run -p 3000:3000 soli-benchmark

# Test endpoints
curl http://localhost:3000/plaintext
curl http://localhost:3000/json

Running TechEmpower Benchmarks

To run the full TechEmpower benchmark suite:

./tfb --test soli

This will run the plaintext and JSON serialization tests against the Soli framework.

Notes

• Database tests are not implemented as Soli MVC currently does not have PostgreSQL support
• The framework uses a production-optimized build with caching enabled
• Worker threads are auto-detected based on available CPU cores
