Java vs Rust: Upload Speed Benchmark – Rust Destroys Java?
⚡ In this video, we put Java and Rust to the test in a real-world file upload speed comparison. Which language handles uploads faster under pressure? Spoiler: Rust wins, and here's why.
🧪 What you'll learn:
Upload speed benchmark: Java vs Rust
Real-world file upload test (small to large files)
Code-level optimizations and performance differences
Why Rust is gaining traction for high-performance backend tasks
🚀 Whether you're a backend developer, performance nerd, or choosing your next tech stack, this test highlights where each language stands in 2025.
🛠️ Tech Stack Used:
Java (OpenJDK 11)
Rust (async with tokio and reqwest)
Test: Uploading files to a local server or cloud endpoint
💡 Key takeaway: Rust’s async model and zero-cost abstractions give it a serious edge in performance-critical scenarios.
