phprust-bench

A simple benchmark project to compare PHP and Rust performance in computing prime numbers.

This project demonstrates how PHP can call a compiled Rust binary via shell_exec() and measure total execution time, while Rust performs the heavy computation efficiently.

With No Jit and Opcache

🚀 Overview

Language	Method	Description
PHP	Pure PHP	Calculates prime numbers using a simple loop and checks for divisibility. Single-threaded.
Rust	Binary (called via PHP)	Compute efficiently.

💻 Server Specs

This project runs on the smallest Droplet size from DigitalOcean (region: SGP1):

PHP-Rust-Bench
512 MB RAM / 10 GB Disk / SGP1 - Ubuntu 25.10 x64

You can also test the benchmark with a custom limit by appending a limit parameter (default = 500,000):

https://phprust-bench.porrapat.com/?limit=400000

The limit defines the upper bound of numbers to check for primes.

The PHP is capped at 2,000,000 but Rust is at 20,000,000 to prevent memory overflow or performance degradation on smaller servers.

🔧 Build & Run

1. Build Rust binary

cargo build --release --bin phprust-bench
cargo build --release --bin phprust-bench-eratos

This produces target/release/phprust-bench (or .exe on Windows).

2. Run from PHP

We locked output at 2,000,000 to protect PHP server. Otherwise for Rust is locked at 20,000,000. You can uncommented there.

---

🧠 Example Output

Rust found 148933 primes up to 2000000 in 0.108 seconds.
Total call time from PHP: 0.154 seconds.

🧩 Cross-Platform Support

• ✅ Windows: uses .exe path (escaped with \\)
• ✅ Linux / macOS: uses ./target/release/phprust-bench

Test on Using gRPC and another server

I use another server to run and connect it using gRPC (4 vCPU)

And it's max (48 vCPU) what we can do
