RPC Edge: Faster, Leaner, and Smarter

Nischit Pradhan

At thirdweb, innovation is in our DNA. We’re excited to share a behind-the-scenes look at how our team is continuously pushing the boundaries to deliver an unparalleled user experience. Today, we're diving into some key upgrades that have transformed our RPC server.

We’ve made a bold move by switching our RPC server to the Bun runtime. This isn’t just a technological upgrade—it’s a leap toward efficiency. With this change, we’ve managed to slash memory usage by 30%. What does that mean for you? More network requests are handled seamlessly, ensuring a smoother and more responsive experience without the need for extra hardware.

Performance matters, and every millisecond counts. By introducing short-term caching into our architecture, we’ve dramatically reduced latency. Our metrics tell the story:

• P90 latency is down by 50%.
• P95 latency has improved by a whopping 300%.

These numbers translate into faster response times and a more robust service, even during peak usage periods.

Understanding every nuance of our system is key to delivering excellence. We’ve integrated fine-grained our Performance Monitoring that drills down into every RPC call. This means we now track method-level usage and latency, giving us a crystal-clear view of performance across the board. With this insight, we’re empowered to act swiftly, optimizing our service before issues can arise.
