Vercel Functions are now faster—and powered by Rust
TL;DR
Vercel Functions previously faced performance limitations that affected application responsiveness. To address this, Vercel has transitioned its serverless functions to be powered by Rust, a systems programming language known for its speed and efficiency.
✦ Why It Matters
Engineers can leverage faster serverless functions to improve application performance and user experience.
Key Takeaways
- Migrate serverless functions to Vercel for improved performance.
- Utilize Rust optimizations for faster cold starts and execution.
- Take advantage of reduced billing durations due to faster processing.
- Explore new CPU and memory options in the Vercel dashboard.
How It Works
The transition to Rust involved rewriting the function initialization and invocation phases, allowing for lower-level language optimizations. This change improved performance by streamlining processes like environment variable reading and response streaming, which are critical during function execution.
